The unique syntax of PHP is a mixture of C, Java, Perl and PHP's own syntax. It can execute dynamic web pages faster than CGI or Perl. Compared with other programming languages, the dynamic page made by PHP embeds the program in the HTML document for execution, and the execution efficiency is much higher than that of CGI which completely generates HTML tags.
PHP can also execute compiled code, which can realize encryption and optimize code operation, making the code run faster.
PHP's rich support for databases is also one of the reasons for its rapid popularity. It supports the following databases or data files:
Adabas, d, DBA, dBase, dbm, filePro, Informix, InterBase, mSQL, Microsoft SQL Server, MySQL, Solid, Sybase, Oracle, PostgreSQL.

In terms of dynamic pages, compared with other programming languages, PHP embeds programs into htmL documents for execution, and the execution efficiency is much higher than that of CGI which completely generates HTML tags. PHP has very powerful functions, and all CGI functions can be realized in PHP.
3.PHP supports almost all popular databases and operating systems.
