I am using Aptana 3 which is basically a modified version of eclipse, so i think this question is applicable to both
Before I commit code in I like to review my changes via the text compare. It allows me to double check things I have changed.
However although text has been highlighted for changes made it does not keep the php syntax highlights. Is there anyway I can keep the PHP or whatever syntax highlighting when viewing differences?
See screenshot.

This is something that a plugin author must implement, and, it seems that it’s still not implemented for Aptana’s PHP editor, so, the proper thing to have that would be reporting this as a bug to be fixed in a future Aptana Studio 3 version.
