including major websites like Facebook, Digg and WordPress,
there are good reasons why many Web developers prefer it to other server-side scripting languages, such as Python and Ruby.
PHP is faster (updated), and it is the most used scripting language in practice; it has detailed documentation
, a huge community, numerous ready-to-use scripts and well-supported frameworks; and most importantly, it’s much easier to get started with PHP than with other scripting languages (Python, for example). That’s why it makes perfect sense to provide the huge community of PHP developers with an overview of useful tools and resources that can make their development process easier and more effective.
