It is mainly suitable for the field of Web development. PHP's unique syntax mixes C, Java, Perl, and PHP's own syntax. It can execute dynamic web pages faster than CGI or Perl. Compared with other programming languages, dynamic pages made with PHP embed programs into HTML (an application under the Standard Universal Markup Language) document for execution, and the execution efficiency is much higher than CGI that completely generates HTML tags; PHP can also execute compiled code. Compilation can achieve encryption and optimize code running, making the code run faster.
The features of PHP include:
1. PHP’s unique syntax mixes C, Java, Perl and PHP’s own innovative syntax.
2. PHP can execute dynamic web pages faster than CGI or Perl - in terms of dynamic pages, compared with other programming languages,
PHP embeds programs into HTML documents for execution, and the execution efficiency is higher than that of complete The CGI that generates HTML tags is much higher;
