Web Development: PHP ASP RoR AJAX RegExp CSS JS tools scripts

PHP is a popular open-source programming language used primarily for developing server-side applications and dynamic web content, and more recently, other software. The name is a recursive acronym for "PHP: Hypertext Preprocessor".

Famous examples of PHP applications include phpBB and MediaWiki, the software behind Wikipedia. The PHP model can be seen as an alternative to Microsoft's ASP.NET/C#/VB.NET system, Macromedia's ColdFusion system, Sun Microsystems' JSP/Java system, and to the CGI/Perl system.

PHP was designed "from the bottom up to be for the Web." Java, meanwhile, is more suitable for heavy-duty transactional applications whereas .Net is geared specifically toward Windows.
