I ' ve just updated Aptana Studio from 1.5 to 2.0 only to find out this spectacular Aptana PHP plugin is not longer supp Orted and its installation has been removed from the Install Additional view. However, with some tricks we can still install the "old" Aptana 1.5.1 in order to use it. So, in fact we can even install Aptana PHP in Studio 2.0.
Download Aptana Studio 2.0 and install it.
At the Install Additional Features after installing Aptana, close it, what we need isn't here.
From the "Help menu", click on Install New Software ...
Add the Aptana PHP plugin update site. Click on the Add ... button and type the URL http://update.aptana.com/update/php
Choose the Aptana PHP 1.1 and install it. After restarting Studio, the Aptana PHP plugin would be installed and your PHP files would be handled by it.
As you can in the Plugins Manager, Aptana PHP 1.1 is installed (the Duplicate location warning appears because I typed The URL again to this tutorial). I ' ve you already installed Eclipse PDT, make sure for you remove it, or your php files won ' t being handled by Aptana PHP.
So that's it, if you have any issues please let me know.
