I'm trying to install PDT plugin in Eclipse and I get error:

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

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

回答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.

In Ubuntu 14.04 the solution presented by @Manfred did not solve my installation problem.

Then I followed the solution presented in PHPeclipse

Enabling PHP Support

As-standard, Eclipse does not come with support for PHP. This must be added, and added as root.

Launch Eclipse as root from the command line:

    $ sudo eclipse (gksudo causes an unusual warning). 

When the "Welcome to Eclipse" screen is displayed, select Help->Install New Software...

The "Galileo" site must be added, click "Add..." and input:

    Name: Galileo Location: http://download.eclipse.org/releases/galileo/ 

Once this is available, select "Galileo" in the Work with: drop-down list.

Enter "php" into the filter text, two entries should be displayed for "PHP Developer Tools (PDT)"; one under Programming Languages,

another under Web, XML, and Java EE Development. Select both and click "Next >".

Verify that the items you wish to install are displayed on the "Install Details" screen and click "Finish".
Eclipse will need restarted for the update to complete. 

With this complete, you should be able to launch Eclipse under a normal user account and select New->Project...->PHP->PHP Project.
