PHP is a very widley used scripting language and is one of the most common languages used to create websites.
PHP is free to use, and open source and is in most cases the first language someone learns. Unfortunatley as PHP is a weakly typed language it can be easily misused allowing programmers to do things that would not be possible in other languages.
