问题
I have several file extensions, like .module, that I would like to be understood by Eclipse to be PHP - so I get the same syntax highlighting, code completion, etc features as I would if I were editing a .php file. How can I do this?
I went to Window >> Preferences >> General >> File Associations and added *.module to the file types list. When I click on *.module, it now says the associated editors are the PHP Editor and the Text editor.
However, when I open the *.module file to edit it, it gives me an error message:
Unsupported content type in editor. To associate a file extension with a supported content type, please see the Content Types Preferences Page.
What am I doing wrong?
fixed: restarted Eclipse, and now it works.
回答1:
Head to Window -> Preferences. Drill down to General -> Editors -> File Associations. From here you can add your extensions (e.g., *.module) and associate them with your preferred PHP editor.
Then restart Eclipse for the change to take effect.

FYI.
window > preference > general > content types.
Expand '▷Text' and you will find 'PHP Content Type'. Select that.
Then click 'Add' and insert your own extension.

Something extra to be aware of.
I had the same problem, even after installing PDT. Turns out that there was an entry in General=>Content Types=>Text for *.php. Note that this not under General=>Content Types=>Text=>PHP Content Type, which is placed there by PDT. Removing the one under Text fixed the problem for me.
