PHP Coder is an IDE (Integrated Development Environment) especially designed for PHP programmers.
Via a wide integration of the PHP interpreter and official documentation, PHP Coder helps you save time when testing local servers.
Among its best features you can change the code colour in HTML and PHP syntax, to make it more legible, auto-complete the most used text structures, a project administrator, unlimited undo levels, previews, etc.
Apart from all these features offered by PHP Coder, designed especially to help your programming work, it is also a tool that loads more rapidly than others in the same category, and it's free.
