Different language syntax highlighting within same file

I use a program called phpDesigner that highlights PHP, HTML, CSS, JavaScript all separately in the same document. It does code completion for each part, even if you do style="fon...".

I had to move to it since I couldn't find any other program that was so good when working with PHP (and all the other languages it uses at the same time), including Notepad++. The one thing I wish it did was syntax highlight SQL strings within PHP (it does fine with just SQL), but maybe in a future version.

I recently tried out Sublime Text 2 which did very well with highlighting files which contained multiple languages. In my case, it was only HTML+CSS+JS but I'm sure it would work well with PHP.

The app is not as feature rich as notepad++ but it is much more aesthetically pleasing.

The demo version prompts the user to purchase the license once in a while, but there is no time limit.

For those who are trying to embed different languages into each other I've found tool that allows such type of configuration: http://www.freescripteditor.org/

I personally needed PHP embedded into SQL (yes, in that order).

Configuration files are human readable, so you can change them with text editor (there's also GUI in program itself).
