DzSoft PHP Editor helps you write and edit PHP source code. It comes as a small program that offers the necessary tools for writing efficient PHP source code. The application is able to handle HTML code as well. DzSoft PHP Editor runs on all Windows versions and is suitable for both beginners and advanced users.
Although its price might seem a bit too high, I think the application is worth its money. First off, its graphical user-interface is highly customizable. You are allowed to change the size of the main window, hide or show various panels and toolbars, and change its skin. It consists of two tabs: Edit and Run & Preview. Though, it should be noted that in order to preview the results, you need to install a PHP interpreter on your system, as this program doesn't include one.
Another feature that is worth to be mentioned is the application’s ability to save the PHP files directly on an FTP server. Also, in order to help you save time, this utility offers you the opportunity to set various bookmarks which will help you easily navigate to specific regions of the source code. If you are a PHP developer, you should try DzSoft PHP Editor.
