How to enable php tag highlighting in BracketHighlighter?

Question

Sublime Text

Gentlemen, who uses this plugin in the Sublime Text editor, tell me how to turn on the highlighting of php tags in files with the .php extension?

Highlighting works only in .html files, but I need for vorpress .php files.
I tried to figure it out myself, but did not understand how and where it is turned on. Help me to understand.
