Alex Netkachov made a happy discovery recently and wanted to share it, so he blogged about it - the inclusion of his suggestion into the nightly build of the PDT extension for Eclipse:
Happy dreams of PHP developers come true. Yesterday I received a letter from Eclipse PDT bugzilla with notification that my proposition about autocomplete for properties that submitted more than a year ago is implemented in PDT 2.0 nightly builds.
There's a screenshot included in the post and he points to the download page where you can grab the files you'll need.
