I think I have already mentioned in an earlier post that I use PHPEclipse as my IDE. Up to now I had the problem that there was no syntaxhighlighting in .thtml files although I had associated the PHP editor with the .thtml filetype in the Eclipse preferences under “General/Editors/File Associations”. But I missed that I have to associate the .thtml filetype with the “PHP Source file” content type under “General/Content Types”… Anyway, I am happy to have syntaxhighlighting :)
