PHP For Loops

So what’s a loop then? A loop is something that goes round and round. If I told you to move a finger around in a loop, you’d have no problem with the order (unless you have no fingers!) In programming, it’s exactly the same. Except a programming loop will go round and round until you tell it to stop. You also need to tell the programme two other things - where to start your loop, and what to do after it’s finished one lap (known as the update expression).
You can programme without using loops. But it’s an awful lot easier with them. Consider this.
You want to add up the numbers 1 to 4: 1 + 2 + 3 + 4. You could do it like this:

$answer = 1 + 2 + 3 + 4;
print $answer;

Fairly simple, you think. And not much code, either. But what if you wanted to add up a thousand numbers? Are you really going to type them all out like that? It’s an awful lot of typing. A loop would make life a lot simpler. You use them when you want to execute the same code over and over again.
We'll discuss a few flavours of programming loops, but as the For Loop is the most used type of loop, we'll discuss those first.

For Loops

Here’s a PHP For Loop in a little script. Type it into new PHP script and save your work. Run your code and test it out.

<?PHP

$counter = 0;
$start = 1;

for($start; $start < 11; $start++) {

$counter = $counter + 1;
print $counter . "<BR>";

}

?>

How did you get on? You should have seen the numbers 1 to 10 printed on your browser page.
The format for a For Loop is this:

for (start value; end value; update expression) {

}

The first thing you need to do is type the name of the loop you’re using, in this case for. In between round brackets, you then type your three conditions:
Start Value
The first condition is where you tell PHP the initial value of your loop. In other words, start the loop at what number? We used this:

$start = 1;

We’re assigning a value of 1 to a variable called $start. Like all variables, you can make up your own name. A popular name for the initial variable is the letter i . You can set the initial condition before the loop begins, like we did:

$start = 1;

for($start; $start < 11; $start++) {

Or you can assign your loop value right in the For Loop code:

for($start = 1; start < 11; start++) {

The result is the same – the start number for this loop is 1

End Value
Next, you have to tell PHP when to end your loop. This can be a number, a Boolean value, a string, etc. Here, we’re telling PHP to keep going round the loop while the value of the variable $start is Less Than 11.

for($start; $start < 11; $start++) {

When the value of $start is 11 or higher, PHP will bail out of the loop.

Update Expression
Loops need a way of getting the next number in a series. If the loop couldn’t update the starting value, it would be stuck on the starting value. If we didn’t update our start value, our loop would get stuck on 1. In other words, you need to tell the loop how it is to go round and round. We used this:

$start++

In a lot of programming language (and PHP) the double plus symbol (++) means increment (increase the value by one). It’s just a short way of saying this:

$start = $start + 1

You can go down by one (decrement) by using the double minus symbol (--), but we won’t go into that.

So our whole loop reads “Starting at a value of 1, keep going round and round while the start value is less than 11. Increase the starting value by one each time round the loop.”
Every time the loop goes round, the code between our two curly brackets { } gets executed:

$counter = $counter + 1;
print $counter . "<BR>";

Notice that we’re just incrementing the counter variable by 1 each time round the loop, exactly the same as what we’re doing with the start variable. So we could have put this instead:

$counter ++

The effect would be the same. As an experiment, try setting the value of $counter to 11 outside the loop (it’s currently $counter = 0). Then inside the loop, use $counter- - (the double minus sign). Can you guess what will happen? Will it crash, or not? Or will it print something out? Better save your work, just in case!

Create a database for a Survey App

This lesson is part of an ongoing Survey/Poll tutorial. The first part is here: Build your own Survey/Poll, along with all the files you need.

In the previous part of this lesson, you opened the phpMyAdmin screen. With this still open, click on “Please select a database“. Have a look at the items on the drop down list. You should see one called surveytest:

If you can’t see surveytest there, it means you haven’t copied the surveytest folder to the correct place.

If you can see surveytest, select it from the drop down list. You should see the names of two tables appear:

Click on tblQuestions, and you’ll see the Structure for this Table (it’s too big to fit on this page, so click below to see it):

The Structure for the tblQuestions Table (opens in a new window – 59K

Under the Table heading, you’ll see the two tables in this database: answers and tblQuestions. Click on the Browse icon for tblQuestions, as in the image below:

You will be taken to the Field names and Rows in the table:

The Field names run from left to right, and are important. They are:

QID
Question
qA
qB
qC

The tblQuestions table above has four rows of data, one for each question. The QID field is the one to pay attention to. The values in the sample table are q1, q2, q3, and q4. This QID field is the Primary Key in this table. This means that the data in this field has to be unique. You can then use this QID field to identify each row in the table. This same field, QID, is also in the answers table, along with the qA, qB, qC fields. This allows you to select all the records in both tables based on the QID field. You just pull all the records that match. For example, you can say “Select all the records in both tables where the QID field equals q1″.

Take a look at the answers table by clicking the link on the left hand side. Then click on Browse at the top. You should see this:

In the answers table, the unique field (the primary key) is the ID field. This is just an auto incrementing number that you used in an earlier section. You don’t have to worry about this field. But notice that the QID field is also there, along with the same values from the tblQuestions table: q1, q2, q3, and q4. This matching QID field in the answers table is something called a foreign key, in database terminology. Joining data from a primary key in one table to a foreign key in another is common technique in database creation. You do this when you want to keep data separate, and to avoid having too many fields in a single table. It also speeds things up. In our example database, we can keep the questions and answers separate.

(NOTE: If you have some knowledge about databases, you’ll know about Referential Integrity. Unfortunately, phpMyAdmin doesn’t enforce this. So if you delete a row from one table, the corresponding row in another table won’t get deleted – you have to code for that yourself!)

The A, B, and C fields in the answers table record how many people voted for each option of your question. So, for question four (q4) 28 people voted for option A, 127 people voted for option B, and 52 people voted for option C. If you look at the matching row (q4) in the tblQuestions table you’ll see that the question was: Do you believe in UFOs? (These answers were entered by us – it’s not real data!)

Now that you have a good idea about how the database works, let’s go through the code that sets a question.

10 Advanced PHP Tips To Improve Your Programming

PHP programming has climbed rapidly since its humble beginnings in 1995. Since then, PHP has become the most popular programming language for Web applications. Many popular websites are powered by PHP, and an overwhelming majority of scripts and Web projects are built with the popular language.

Because of PHP’s huge popularity, it has become almost impossible for Web developers not to have at least a working knowledge of PHP Training in Jaipur . This tutorial is aimed at people who are just past the beginning stages of learning PHP and are ready to roll up their sleeves and get their hands dirty with the language. Listed below are 10 excellent techniques that PHP developers should learn and use every time they program. These tips will speed up proficiency and make the code much more responsive, cleaner and more optimized for performance.

1. Use an SQL Injection Cheat Sheet

A list of common SQL injections.

SQL injection is a nasty thing. An SQL injection is a security exploit that allows a hacker to dive into your database using a vulnerability in your code. While this article isn’t about MySQL, many PHP programs use MySQL databases with PHP, so knowing what to avoid is handy if you want to write secure code.

Furruh Mavituna has a very nifty SQL injection cheat sheet that has a section on vulnerabilities with PHP and MySQL. If you can avoid the practices the cheat sheet identifies, your code will be much less prone to scripting attacks.

2. Know the Difference Between Comparison Operators

PHP’s list of comparison operators.

Comparison operators are a huge part of PHP, and some programmers may not be as well-versed in their differences as they ought. In fact, an article at I/O reader states that many PHP developers can’t tell the differences right away between comparison operators. Tsk tsk.

These are extremely useful and most PHPers can’t tell the difference between == and ===. Essentially, == looks for equality, and by that PHP will generally try to coerce data into similar formats, eg: 1 == ‘1′ (true), whereas === looks for identity: 1 === ‘1′ (false). The usefulness of these operators should be immediately recognized for common functions such as strpos(). Since zero in PHP is analogous to FALSE it means that without this operator there would be no way to tell from the result of strpos() if something is at the beginning of a string or if strpos() failed to find anything. Obviously this has many applications elsewhere where returning zero is not equivalent to FALSE.

Just to be clear, == looks for equality, and === looks for identity. You can see a list of the comparison operators on the PHP.net website.

3. Shortcut the else

It should be noted that tips 3 and 4 both might make the code slightly less readable. The emphasis for these tips is on speed and performance. If you’d rather not sacrifice readability, then you might want to skip them.

Anything that can be done to make the code simpler and smaller is usually a good practice. One such tip is to take the middleman out of else statements, so to speak. Christian Montoya has an excellent example of conserving characters with shorter else statements.

Usual else statement:

if( this condition )
{
$x = 5;
}
else
{
$x = 10;
}

If the $x is going to be 10 by default, just start with 10. No need to bother typing the else at all.

$x = 10;
if( this condition )
{
$x = 5;
}

While it may not seem like a huge difference in the space saved in the code, if there are a lot of else statements in your programming, it will definitely add up.

4. Drop those Brackets

Dropping brackets saves space and time in your code.

Much like using shortcuts when writing else functions, you can also save some characters in the code by dropping the brackets in a single expression following a control structure. Evolt.org has a handy example showcasing a bracket-less structure.

if ($gollum == 'halfling') {
$height --;
}

This is the same as:

if ($gollum == 'halfling') $height --;

You can even use multiple instances:

if ($gollum == 'halfling') $height --;
else $height ++; 
 
if ($frodo != 'dead')
echo 'Gosh darnit, roll again Sauron';
 
foreach ($kill as $count)
echo 'Legolas strikes again, that makes' . $count . 'for me!';

5. Favour str_replace() over ereg_replace() and preg_replace()

Speed tests show that str_replace() is 61% faster.

In terms of efficiency, str_replace() is much more efficient than regular expressions at replacing strings. In fact, according to Making the Web, str_replace() is 61% more efficient than regular expressions like ereg_replace() and preg_replace().

If you’re using regular expressions, then ereg_replace() and preg_replace() will be much faster than str_replace().

6. Use Ternary Operators

Instead of using an if/else statement altogether, consider using a ternary operator. PHP Value gives an excellent example of what a ternary operator looks like.

//PHP COde Example usage for: Ternary Operator
$todo = (empty($_POST[’todo’])) ? ‘default’ : $_POST[’todo’]; 
 
// The above is identical to this if/else statement
if (empty($_POST[’todo’])) {
$action = ‘default’;
} else {
$action = $_POST[’todo’];
}
?>

The ternary operator frees up line space and makes your code less cluttered, making it easier to scan. Take care not to use more than one ternary operator in a single statement, as PHP doesn’t always know what to do in those situations.

7. Memcached

Memcached is an excellent database caching system to use with PHP.

While there are tons of caching options out there, Memcached keeps topping the list as the most efficient for database caching. It’s not the easiest caching system to implement, but if you’re going to build a website in PHP that uses a database, Memcached can certainly speed it up. The caching structure for Memcached was first built for the PHP-based blogging website LiveJournal.

PHP.net has an excellent tutorial on installing and using memcached with your PHP projects.

8. Use a Framework

CakePHP is one of the top PHP frameworks.

You may not be able to use a PHP framework for every project you create, but frameworks like CakePHP, Zend, Symfony and CodeIgniter can greatly decrease the time spent developing a website. A Web framework is software that bundles with commonly needed functionality that can help speed up development. Frameworks help eliminate some of the overhead in developing Web applications and Web services.

If you can use a framework to take care of the repetitive tasks in programming a website, you’ll develop at a much faster rate. The less you have to code, the less you’ll have to debug and test.

9. Use the Suppression Operator Correctly

The error suppression operator (or, in the PHP manual, the “error control operator“) is the @ symbol. When placed in front of an expression in PHP, it simply tells any errors that were generated from that expression to now show up. This variable is quite handy if you’re not sure of a value and don’t want the script to throw out errors when run.

However, programmers often use the error suppression operator incorrectly. The @ operator is rather slow and can be costly if you need to write code with performance in mind.

Michel Fortin has some excellent examples on how to sidestep the @ operator with alternative methods. Here’s an example of how he used isset to replace the error suppression operator:

if (isset($albus))  $albert = $albus;
else                $albert = NULL;

is equivalent to:

$albert = @$albus;

But while this second form is good syntax, it runs about two times slower. A better solution is to assign the variable by reference, which will not trigger any notice, like this:

$albert =& $albus;

It’s important to note that these changes can have some accidental side effects and should be used only in performance-critical areas and places that aren’t going to be affected.

10. Use isset instead of strlen

Switching isset for strlen makes calls about five times faster.

If you’re going to be checking the length of a string, use isset instead of strlen. By using isset, your calls will be about five times quicker. It should also be noted that by using isset, your call will still be valid if the variable doesn’t exist. The D-talk has an example of how to swap out isset for strlen:

PHP - Origin, Application, Growth and Scope!

PHP is the most widely used scripting language, majorly used for web-development and application development, all across the globe. Basically, PHP is used for open source, general-purpose scripting language. PHP started as Personal Home Page tools, developed by Rasmus Lerdorf in 1995 and then it was proved so useful in various developments of websites & applications that it grew rapidly and became full-featured language that it is in today's market and it further acquired the name "PHP Hypertext Preprocessor" along the way to represent its expanded abilities. PHP Training in Jaipur is easy to use, fast, free, secure and versatile.

You must invest some time and learn PHP from a professional institute, if you want to be a successful website developer. To work on all operating systems like Linux, MAC, windows and others, it is very important to learn and work on this language practically. Primary benefit is that even if you are a non-programmer and a learner, you can grasp this language easily without any problem. PHP commands are quite simple, embedded with the easy HTML tags and coding. PHP commands are operated on a server so that it delivers high quality interactive web page.

Nowadays, there is huge demand in market for PHP developers for both experts and fresher. Originally, such intricately designed courses meet the requirements of both first timers and proficient developers. PHP training centers will teach you on real life projects to enhance your practical knowledge in leaps. Main advantage of PHP is that it is a free download and doesn't cost you a penny if you want to practice at your own desktop at home. There are many experts that can guide you for the most appropriate course for you according to your present skills and work experience.

PHP training has helped a number of people find employment. There are an ample number of opportunities for various "PHP Frameworks Training courses" as per industry demands. For those students who would like to gain more depth knowledge and understanding of various frameworks, there are few programs designed by PHP Experts. As the industry is growing rapidly, the latest amenities and state-of-art infrastructure are offered by the various institutions for better concentration and learning among students.

In recent time PHP developers have to struggle with coding and think in an object oriented manner, gain high traffics, research more than ever. Knowing user interface practices and dealing with different device resolutions isn't their concern but few firms are asking for it.

Overall, PHP is well known as the popular programming language and its dynamic development with time, which is now used to develop dynamic online stores, shopping carts, and various e-commerce applications for secured and convenient manner. Today PHP web development is spreading its wings like other technologies. For developing very flexible dynamic sites, PHP is one of the best choices in web development. For creating dynamic websites, web designer usually prefer PHP as the programming language because this script can be easily embedded into HTML coding. And if one talks about its scope then it's the best place for marketing and polishing of your talent.

What Is a PHP Template?

Websites have become a must not only for businesses but for many personal and artistic projects as well. There are many ways to create a website, from hiring a full-scale web development company, to doing it yourself by hand, to premade theme-based websites. Each of these approaches has its benefits and drawbacks, but using a PHP template offers the best features of all three.

PHP is a common coding language used to build websites. There are nearly 250 million websites built in PHP on over 2 million servers. These websites run the full range from visually intense to minimalistic, from animated to static media, and from blogging to e-commerce to simple informational pages.

While PHP Training in Jaipur is among the preferred coding languages for web developers, many users are not experienced coders and would not feel comfortable building their own website from scratch. And that's why the idea the PHP template was invented.

A PHP template is essentially a fully coded, full designed website that is missing only content (the words and pictures you want to include). All the PHP files are provided with the template, including any CSS (visual style programming), and are ready to upload to your server to make your site go live. But even better, because you have access to every line of code in the template, you have total freedom to change any aspect of the site you'd like to change: if the border is brown and you want it to be blue, you can do that; if you want the margins wider, or the header bigger, or to change the default font - you can do that.

Of course, there are a variety of platforms that offer customizable "theme based" websites, but many have very limited customization. Typically, when you buy a "theme" for a web platform you can only change the CSS, or visual styling, and have limited access to the underlying code. That means you can make only the most cosmetic changes. With a PHP template you can make deep-level changes to the framework and functionality of the website itself.

In other words, a PHP template provides more customization than a theme-based website, requires little coding knowledge and yet costs a fraction of hiring a professional designer. A designer can easily charge over $200 per hour, whereas you can buy a huge collection of PHP templates for less than $40.

Ultimately, the amount of coding skill you need to use PHP templates is up to you. If you want to make only minor changes or use a template as-is, you might not need any coding experience at all. If you're an experienced web designer you can use the template as a jumping off point and build something completely unique in record time. PHP templates are the most flexible way of building attractive websites.

Benefits of PHP Programming in Contract Programming Industry

PHP is a scripting language originally designed for producing dynamic web pages. While PHP was originally created by Rasmus Lerdorf in 1995, the main implementation of PHP is now produced by The PHP Group and serves for PHP as there is no formal specification. PHP is free software released under the PHP License and is a widely-used general-purpose scripting language that is especially suited for web development and can be embedded into HTML. It generally runs on a web server, which is configured to take PHP code as input and create web page content as output. It can be deployed on most web servers and on almost every operating system and platform free of charge. PHP Training in Jaipur is installed on over 20 million websites and 1 million web servers.

Using Cookies with PHP

Cookies allow the webmaster to store information about the site visitor on their computer to be accessed again the next time they visit. One common use of cookies is to store your username and password on your computer so you don't need to login again each time you visit a website. Cookies can also store other things such as your name, last visit, shopping cart contents, etc.

The main difference between a cookie and a session is that a cookie is stored on your computer, and a session is not. Although cookies have been around for many years and most people do have them enabled, there are some who do not. Cookies can also be removed by the user at any time, so don't use them to store anything too important.

A cookie is set with the following code: setcookie(name, value, expiration)

 <?php 
 $Month = 2592000 + time(); 
 //this adds 30 days to the current time 
 setcookie(AboutVisit, date("F jS - g:i a"), $Month);
 ?> 

The above code sets a cookie in the visitor's browser called "AboutVisit". The cookie sets the value to the 
     current date
     , and set's the expiration to be be in 30 days (2592000 = 60 seconds * 60 mins * 24 hours * 30 days.) 
     

Now let's retrieve the cookie.
<?php 

if(isset($_COOKIE['AboutVisit']))
 { 
 $last = $_COOKIE['AboutVisit']; 
 echo "Welcome back! <br> You last visited on ". $last; 
 } 
 else 
 { 
 echo "Welcome to our site!"; 
 } 
 ?>

This code first checks if the cookie exists. If it does, it welcomes the user back and tells them when they last visited. If they are new, it skips this and prints a generic welcome message. TIP: If you are calling a cooking on the same page you plan to set one - be sure you retrieve it first, before you overwrite it!
To destroy the cookie, simply use setcookie again, only set the expiration date to be in the past. This is often done when you 'logout' of a site. Here is an example:

 <?php 
 $past = time() - 10; 
 //this makes the time 10 seconds ago 
 setcookie(AboutVisit, date("F jS - g:i a"), $past);
 ?> 

REMEMBER: Cookies need to be set in the header. This means they must be sent before any HTML is set to the page, or they will not work.
