Cannot complete the install because one or more required items could not be found.
  Software being installed: PHP Development Tools (PDT) 3.1.2.201212211235 (org.eclipse.php.feature.group 3.1.2.201212211235)
  Missing requirement: PDT Debug UI Plug-in 3.1.2.201212211235 (org.eclipse.php.debug.ui 3.1.2.201212211235) requires 'bundle org.eclipse.dltk.debug.ui [4.0.0,5.0.0)' but it could not be found

Answer 1

dgolovins answer worked for me.

First install Dynamic Language Toolkit: Help-->Install New Software --> Add --> Location: http://download.eclipse.org/technology/dltk/updates-dev/4.0-stable/

Then install PDT: Help-->Install New Software --> Add --> Location: http://download.eclipse.org/tools/pdt/updates/latest

Answer 2

This message is awful and means that org.eclipse.dltk.debug.ui with 4.0.0 <= version <5.0.0 is not available in your eclipse installation or form available eclipse update sites in Install dialog.

Add Eclipse Dynamic Language Toolkit update site in eclipse Install dialog and then try to install PDT again.
