PHPEdit
PHPEdit is a commercial IDE developed by the French company WaterProof SARL. It is written in Delphi and runs on the Microsoft Windows operating system, and is designed mainly for the PHP language, but supports many other languages such as CSS, HTML, JavaScript, INI, PHPEditScript, PlainText, SQL, XML, and XSLT. PHPEdit currently costs €89.00 despite the most recent version being released in 2012. A free license is available, but only for non commercial use (personal homepage or own studies).
As of December 2015, both PHPEdit and Waterproof websites seem to be dead ; product status is unknown.
