Linux Using grep to display filenames

Question

Is there any way I can use grep just to show the filenames and not anything else. I'm trying this:

find . -iname "*php" -exec grep -H myString {} \;

Do I have to use xargs cause I cannot find anything related to grep to do this?

You need t use -l flag with grep(lowercase L). From Unix Docs:

-l
    (The letter ell.) Write only the names of files containing selected
    lines to standard output. Pathnames are written once per file searched.
    If the standard input is searched, a pathname of (standard input) will
    be written, in the POSIX locale. In other locales, standard input may be
    replaced by something more appropriate in those locales.
