[OT / PHP-SYNTAX-MODEL] C, Perl or something ad hoc ?

First of all my apologies for using this list. I'm mantaining an Emacs-Lisp mode (html-helper-mode.el) meant to deal with PHP/JSP/ASP where for the scritp blocks the mode narrows the editing to the block and activates another mode with a language more suited for the script. Until now I used C-mode for PHP but an user suggested to use Perl. I admit that my knowledge of PHP is "I know it exist and had time to give it a brief test" so I ask you : What is better to use for editing PHP script blocks ? c-mode ? perl-mode ? Have I to write a new mode from the two above (if you can add some suggestion on this subject, thank you very much) ? Again my apologies for disturbing you, but I think this is the place to get an "authoritative answer". Thanks in advance.
