Since the July 13, 2004 official release of the PHP5, the number of people learning PHP has increased. But the popularity of PHP is still in the initial stage, most computer enthusiasts also know little about PHP, it is necessary to increase publicity efforts, so that more people understand the learning and use of PHP for our work services. PHP is the abbreviation of English hypertext preprocessor (hypertext preprocessor), it is a server-side HTML scripting/programming language, is a simple, object-oriented, interpretive, robust, secure, very high performance, independent of the architecture, portable, A dynamic scripting language. PHP quickly and quickly in the style of the development of the web system occupies an important position. PHP itself provides a wealth of functions and functions.

PHP began its planned development in 1994 Rasmus Lerdorf. In 1995, Personal home Page tools (PHP tools) began publishing the first release. In this earlier version, simple features such as guest message book, visitor counter, etc. were provided. In 1995 years, the second edition of PHP asked the city, named Php/fi (Form interpreter). In which the support of the mSQL, has laid the PHP in the Dynamic Web development impact. At the end of 1996, there were 15,000 Web sites using Php/fi, and in 1997 years the Web site using PHP/FI grew to over 50,000. In 1997, the third edition of the development Plan was launched, and the development team joined the Zeev Suraski and Andi Gutmans, and the third edition was named PHP3. The PHP3 features of the Apache server, coupled with its constant updating and new functionality, and its almost total support for all mainstream and Non-mainstream databases, and its ability to perform efficiently at high speeds, has made PHP more than 150,000 of its web sites in 1999 years! May 2000, PHP 4.0 officially released. It uses the Zend (Zeev + Andi) engine, provides higher performance, and includes other key features, such as support for more WEB servers; HTTP Sessions support; output cache (outputs buffering) , a more secure way to handle user input and some new language constructs. PHP 4.0 is a more efficient, more reliable Dynamic Web page development tool that runs faster than PHP 3.0 in most cases, and its script description is more powerful and complex, and the most notable feature is the increase in rate ratios. Until last July, PHP5 came out. For both the PHP language itself and the PHP user, the PHP5 release is a landmark version. The birth of PHP5, so that PHP programming into a new era. The adoption of Zend II engine, complete object model and improved syntax design. Eventually makes PHP a fully designed, truly object-oriented scripting language. We expect that the advent of PHP5 will bring the entire PHP community a new round of library and application development improvements.

The biggest advantage of using PHP programming is that learning this programming language is very easy as well as its rich library. We can guess how to accomplish a particular task, even if you don't know exactly what function you need to use. PHP is a server-side scripting language that is easy to learn and use. With minimal programming knowledge you can use PHP to create a truly interactive web site. PHP is one of the tools that will allow you to generate dynamic Web pages. PHP Web files are treated as generic HTML Web pages, and you can edit PHP in the normal way you edit HTML.

PHP is completely free, and you can download it free from the official PHP site (http://www.php.net) without spending money. PHP complies with the GNU Public License (GPL), under which many popular software such as Linux and Emacs are born. You can gain unlimited access to the source code, and even add the features you need to yourself. PHP can be run on most Unix platforms, Gun/linux and Microsoft Windows platforms.
