Since php5 was officially released on July 13, 2004, more and more people are learning PHP. However, the popularity of PHP is still in its infancy, and most computer enthusiasts still know little about PHP. It is necessary to increase publicity efforts so that more people understand, learn and use PHP to serve our work. PHP is the abbreviation of English Hypertext PReprocessor (Hypertext Preprocessor). It is a server-side HTML script/programming language. It is a simple, object-oriented, interpreted, robust, safe, and extremely performant A high-performance, architecture-independent, portable, dynamic scripting language. PHP has quickly occupied an important position in web system development with its convenient and fast style. PHP itself provides a rich and large number of functions and functions. PHP, an open source scripting language, is becoming one of the most popular web application programming languages in the world.
PHP was originally planned and developed by Rasmus Lerdorf in 1994. The first version was released in 1995 as Personal Home Page Tools (PHP Tools). In this early version, simple functions such as guest book and visitor counter were provided. In mid-1995, the second version of PHP was launched on the market, named PHP/FI (Form Interpreter). mSQL support was added, which has since established PHP's influence in dynamic web development. At the end of 1996, there were fifteen thousand Web sites using PHP/FI; by mid-1997, the number of Web sites using PHP/FI had grown to more than fifty thousand. In mid-1997, the development plan for the third version began. The development team joined Zeev Suraski and Andi Gutmans, and the third version was named PHP3. PHP3 is closely integrated with the Apache server; coupled with its continuous updates and new features; and its support for almost all mainstream and non-mainstream databases; and its high-speed execution efficiency, PHP became the most popular website in mid-1999 More than 150,000! In May 2000, PHP 4.0 was officially released. It uses the Zend (Zeev + Andi) engine to provide higher performance, and also includes other key features, such as: support for more web servers; HTTP sessions support; output buffering; and more secure processing of users Input methods and some new language structures. PHP 4.0 is a more efficient and reliable tool for dynamic web page development. It runs faster than PHP 3.0 in most cases. Its script description is more powerful and more complex. The most significant feature is the increase in speed ratio. Until July last year, PHP5 came out. The release of PHP5 is considered a milestone version for both the PHP language itself and PHP users. The birth of PHP5 has brought PHP programming into a new era. The adoption of Zend II engine, complete object model and improved syntax design. Finally, PHP becomes a fully designed scripting language with true object-oriented capabilities. We predict that the emergence of PHP5 will bring a new round of peak improvements in various library and application development to the entire PHP community.
The biggest benefit of programming with PHP is how easy it is to learn this programming language and its rich libraries. Even if we don't know much about the functions we need to use, we can guess how to accomplish a specific task. PHP is a server-side scripting language that is easy to learn and use. With very little 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 web page files are treated as ordinary HTML web page files, and when editing, you can write PHP using the conventional method of editing HTML.
PHP is completely free, no need to spend money, you can download it freely from the PHP official site (http://www.php.net). PHP complies with the GNU Public License (GPL), under which many popular software such as Linux and Emacs were born. You have unlimited access to the source code and can even add the features you need. PHP can run on most Unix platforms, GUN/Linux and Microsoft Windows platforms. Information on how to install PHP on a Windows PC or Unix machine can be found on the PHP official site. The installation process is simple.
PHP is quickly becoming a standard, general-purpose, object-oriented scripting language, becoming a more attractive technology than before. We are not here to discuss PHP technology or skills, but to focus on the introduction. I believe that through understanding, more people will like the PHP language, and my purpose will be achieved.
The above has introduced the development of the PHP language for web programming, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
