What is PHP and ASP, and what is the difference between them?

PHP is a programming language for computers used to generate dynamic content on the Internet. ASP is not a language, but a programming structure, and it uses scripts (VBScript, JScript, PerlScript or Python) processed by the server to generate dynamic content on the web.

In practice, PHP runs on any platform, while ASP is restricted to the Windows system. In terms of learning, PHP is better accepted by the developers due to its simplicity, while ASP is taken as more limited. Cost-wise, the PHP code is a free; that is why it has no structure cost, while ASP requires licenses, because it is not an open system.
