Ubuntu :: Finding A Html And Php Editor

I am learning to do some html, php and css. I read that a normal word processor will not do. Here is what I am suppsed to use... Before you settle on a text editor, make sure it has the following features: Supports syntax highlighting for HTML, CSS, Javascript and PHP. you to code and debug faster by visually separating the different elements of the file. For example, such a text editor might highlight PHP code in blue and HTML code in red. Automatic error highlighting for HTML, CSS, Javascript and PHP. you catch errors in your programs while you are writing your code before these errors are detected when you run your program in Zen Cart. For example, if you fail to specify a closing tag for your HTML code, the editor uses a red underline to highlight the offending HTML tag.
