PHP (foreign name: PHP: Hypertext Preprocessor, Chinese name: "Hypertext Preprocessor") is a powerful server-side scripting language for creating dynamic interactive sites.
PHP is universal and open source.
PHP syntax absorbs the characteristics of C language, Java and Perl, which is easy to learn and widely used. It is mainly suitable for the field of Web development.

Compared with other programming languages, dynamic pages made with PHP embed the program into the HTML (an application under the standard universal markup language) document for execution, and the execution efficiency is higher than that of completely generating HTML tags. CGI is much higher; PHP can also execute compiled code. Compilation can achieve encryption and optimize code running, making the code run faster.
