What Is PHP?

The abbreviation PHP stands for PHP Hypertext Preprocessor.

PHP first originated in 1995 and is a very powerful (and currently the most popular) scripting language which can add dynamic content to your web pages. As HTML controls the way a website looks, PHP controls more how a website functions.

Many popular website platforms operate using PHP, such as blogs, forums and online shopping carts. It is currently estimated that over 20 million websites use PHP in one form or another.

Why Should I Learn PHP?

PHP can add a plethora of functionality and dynamic content to your website. Instead of having static HTML web pages that never change, you can do everything from sending form results by email to building a giant online mall through the use of PHP!

Since PHP is one of the top server-side scripting languages, as a website designer or programmer, it would be to your advantage to learn PHP.

These free online PHP lessons will help you to learn PHP one step at a time. All of the common PHP functions and statements are found here along with information on PHP syntax and how to setup your PHP pages, making it easier for you to learn PHP.

As mentioned above, each topic is listed in alphabetical order to your right. The lessons are written to be as simple as possible while giving you all the information you need to know in order to learn PHP correctly.

Other PHP Information

Since the release of PHP version 4 in 2000, PHP has been increasing in popularity year by year. PHP 5 was released in 2004 and is now considered one of the top languages in server-side scripting.

It is important to note that as a server-side scripting language, the code itself is executed on the Internet server and is returned to the end user as HTML via their browser. Therefore, PHP can only be run on an Internet server that has a PHP interpreter installed, which is not an issue with any mainstream web host.

PHP has many open-source libraries included with its core build, and many more are easily available. Extensions exist to help PHP interface with a number of systems including IRC, multiple compression formats, and Windows API. Other extensions exist to allow PHP to generate file formats on-the-fly, such as a popular extension which allows PHP to create Macromedia Flash movies.

Much of the popularity surrounding PHP has to do with the simplicity of its syntax, making it an easy language to master.
