Dev-PHP

Dev-PHP is a handy and reliable Integrated Development Environment that targets PHP programmers. It includes all of the features required for a development platform and can assist in writing and compiling scripts.
The IDE also integrates PHP-GTK, which is a PHP extension that facilitates bindings inside GTK+ projects through an object-oriented interface, which makes the whole building process easier.
Dev-PHP comes inside a lightweight package and is easy to deploy and setup. It is a cross-platform project, which means commercial use is permitted, regardless of the industry you’re activating in.
The program adopts an intuitive and user-oriented interface that sports a familiar look for developers who have worked with similar IDEs before. You can start a new script from scratch or open an existing one in order to edit and compile it.
Most of the GUI is reserved for the actual code writing process, while the rest of the functionality is encased inside compact menus and a quick toolbar with shortcuts to the most common functions.
Besides basic features such as search, replace, go to line and formatting options, you can also experiment with more advanced tools such as Xdebug (a popular code debugger) and the PHP-GTK, which was discussed above.
Other highlights include preview functions for the scripts, a syntax highlighter with support for multiple programming languages, a wizard that generates email functions and the possibility to insert tables.
In conclusion, Dev-PHP comes across as a full-featured and comprehensive development environment that leverages the power of third-party components such as Xdebug and PHP-GTK in order to make the experience of the PHP developer complete.
