Database support: PHP supports a variety of mainstream and non-mainstream databases, such as: Adabas D, DBA, dBase, dbm, filePro, Informix, InterBase, mSQL, MySQL, Microsoft SQL Server, Solid, Sybase, ODBC, oracle, oracle 8, PostgreSQL, etc. Among them, PHP and MySQL are now an excellent combination, and their combination can run across platforms.

4. Object-oriented programming: PHP provides classes and objects. In order to realize object-oriented programming, PHP4 and higher versions provide new functions and features, including object overloading, reference technology, etc.

5. Fast version update: Compared with ASP, which is only updated once every few years, PHP's update speed is much faster, because PHP is updated every few weeks.

6. Rich functions: From object-based design, structured features, database processing, network interface applications, secure coding mechanisms, etc., PHP covers almost all functions of all websites.

7. Scalability: Traditionally, the interaction of web pages is achieved through CGI. The scalability of CGI programs is not ideal because it opens a separate process for each running CGI program.
