Below I've provided a brief overview of three brilliant code editors useful for all round editing of PHP, HTML, CSS, JavaScript and more. Even though it is a worthwhile skill to be able to code in Notepad, these tools make the life of a programmer / web developer just that little bit easier!

Aptana IDE

Aptana is a robust, JavaScript-focused IDE for building dynamic web applications. Some features are outlined below:

• Code Assist on JavaScript, HTML, and CSS, including your own JavaScript functions
• Outliner that gives a snapshot view of your JavaScript, HTML, and CSS code structure
• Support for Aptana UI customization and extensions
• Error and warning notification for your code

Aptana is available for Windows, Macinstosh and Linux.
