I do not have enough comments to add a comment, so I will talk about the accepted answer here.
SHIFT+CONTROL+OPTION+<LETTER> displays a menu displaying all grammars starting with <LETTER> . Therefore, if you want to return PHP, just press SHIFT+CONTRL+OPTION+P , and then a list of languages ββstarting with "P" will appear. You can select one from the list by clicking the corresponding number (on my computer, it is 2 ).
