i have created a new file with no extension then i changed the file extension to php but the IDE doesn't associate the file type. I have tried to remove manually the extension and then use the file > associate to a file type option on the IDE and it works but when i try to add the extension to the file it removes that association and i see the file as plain text.
Also I have tried to invalidate the cache and restart and doesn't work either.
It happens only when i try to use that specific name. If a change the name to something else the IDE automatically associates the file type.
