Since the official release of PHP5 on July 13, 2004, more and more people have been learning PHP. But the popularity of PHP is still in its infancy, most computer enthusiasts know little about PHP, it is necessary to increase publicity efforts, so that more people learn to learn and use PHP for our work services. PHP is an abbreviation for the English hypertext Preprocessor (hypertext preprocessor), which is a server-side HTML scripting/programming language that is simple, object-oriented, interpreted, robust, secure, highly performance-independent, architecture-free, portable, A dynamic scripting language. PHP quickly and quickly in the style of web system development occupies an important position. PHP itself provides a wealth of functions and functions. As an open source scripting language, PHP is becoming one of the most popular Web application programming languages in the world.
PHP initially began planning for development in 1994 Rasmus Lerdorf. In 1995, Personal Home Page tools (PHP tools) began publishing the first release. In this earlier version, simple functions such as guest message book, guest counter, etc. were provided. In 1995, the second edition of PHP asked the city, named Php/fi (Form interpreter). With the support of MSQL, PHP has since established its influence on dynamic web development. At the end of 1996, there were 15,000 Web sites using Php/fi, and in 1997 years, Web sites with Php/fi grew to more than 50,000. In the 1997 years, the third edition of the development Plan began, the development team joined Zeev Suraski and Andi Gutmans, and the third edition was named PHP3. PHP3 is closely integrated with the Apache server, plus it constantly updates and adds new features, and it supports virtually all mainstream and non-mainstream databases, and it can execute efficiently at high speeds, making PHP more than 150,000 in 1999 years of use! In May 2000, PHP 4.0 was officially released. It uses the Zend (Zeev + Andi) engine to provide higher performance and includes other key features such as support for more WEB servers, HTTP sessions support, output caching (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, its script description is more powerful and more complex, and the most notable feature is the increase in rate ratio. Until last July, PHP5 was invented. The PHP5 release is a milestone version for both the PHP language itself and the PHP user. The birth of PHP5, so that PHP programming into a new era. Zend II engine Adoption, complete object model, improved grammar design. Eventually makes PHP a well-designed scripting language with real object-oriented capabilities. We anticipate that the advent of PHP5 will bring a new round of library and application development improvements to the entire PHP community.
The biggest benefit of using PHP programming is that it is very easy to learn this programming language and its rich library. Even if we don't know much about the functions that need to be used, we can guess how to accomplish a specific task. PHP is a server-side scripting language that is easy to learn and use. With minimal programming knowledge, you can use PHP to build a truly interactive web site. PHP is one of the tools that allows you to generate dynamic Web pages.

PHP is rapidly becoming a standard, multipurpose, object-oriented scripting language that has become a more attractive technology than ever before. We are not here on the technique or technique of PHP, but rather on the introduction, I believe that by understanding there will be more people like the PHP language, so that my purpose is achieved.
The above introduces the development of Web programming PHP language, including the content, I hope the PHP tutorial interested in a friend to help.
