Choose standard program to open_x_file

[Can]

How can I permanently set that all files ending with .php will open in a specific program ?

I have done the whole right-click -> Open With -> choose program select "Always open with". But it only affects that selected file, and not every file ending with .php


Thanks in advance

right click on the file and go to get info, than click on open with, and choose the program. then click change all.
