It's your third line that's at fault.

(add-hook 'c++-mode-hook 'my-php-mode-hook) says "Add the function
my-php-mode-hook to the list of functions which is called whenever
C++ MODE is started."

Replace "c++-mode-hook" with "php-mode-hook", giving this:
(add-hook 'php-mode-hook 'my-php-mode-hook)

[Or, if you'd already written that and merely made a typo when composing
your article (it happens to the best of us) come back again!]

No, comment-column is part of the Emacs base itself.  (Note: variables
which are part of a package have a prefix indicating this:  If
current-column had belonged to CC Mode, it would have been called
"c-comment-column").
