Rasmus Ledorf, a Danish computer programmer, introduced the first version of PHP in 1995. He called the initial set of codes the 'Personal Home Page Tools,' which he used as a code to track visitors looking at his online resume. After some time, he added more functionality to the script and released the source code to everyone. Ledorf continued improving and developing PHP by himself until 1997. During that same year, two more programmers, Andi Gutmans and Zeev Zuraski, coordinated with Ledorf to create PHP 3.0. This version was the first to resemble the current popular PHP most programmers use today. It has more functionality and capabilities and was officially called 'PHP: Hypertext Preprocessor.' The latest PHP is version 5, with several release updates. It still resembles the functionality of version 3.0, but with added features. It mainly runs through the 'Zend Engine 2.0.'
Advantages
There are four major advantages when using PHP: accessibility, compatibility, simplicity and extensive community support. Because PHP is open source, access has no restrictions. Programmers interested in using PHP only need to download the scripts, without paying a single cent. It runs in all types of Operating Systems and is also compatible with the most popular Web servers, including Apache and IIS. Programmers also don't have to spend a lot of time learning PHP because its language is related to Perl and C, two of the most popular coding languages. Lastly, PHP has a large online community support. Since it's free, a lot of other programmers share scripts and give advice on how to improve the system.
Popularity
As of May 2011, there are more than 25 million websites that run on PHP. Most webmasters prefer to use the language because PHP was created to work on Web development. PHP can also be integrated to HTML codes, allowing easier coding and flexibility when building websites.
Limitations
Although using PHP is simple, experienced programmers are usually required when building complex and large websites. PHP has a lot of extensions and other add-ons, and an inexperienced programmer may get confused sorting through and checking all of the available scripts. Also, codes can sometimes become complex when programmers want to achieve a very specific function. Lastly, because PHP is mainly a language designed for Web development, building large websites requires programmers to know HTML, JavaScript and CSS.
