Wanting to try out something new in the IDE department, Ben Ramsey reached for the Eclipse PHP IDE to see how it ran. His latest post details the installation process he went through to get things up and running.
I already had a working Eclipse installation that I had used to try out PHPeclipse for Eclipse (not to be confused with the PHP IDE), so I didn't want to bother downloading a brand new full package of Eclipse that includes the PHP IDE and all its requirements. So, I set about on a tedious journey to figure out how to install PHP IDE using the Eclipse Update Manager. These are my notes.
There's really only three main steps he went through: disable PHPeclipse (if installed), install the other software needed by PHP IDE, and finally, install the PHP IDE plugin itself. That's it (assuming all goes well with the prerequisites).
You can grab the latest copy of the Eclipse PHP IDE from the project's website.
