You will not be able to do this with PCRE. You need something that can
track state because double quotes can appear within HTML outside of PHP
blocks, within HEREDOC, within double-quoted strings when backslashed,
and within single quoted strings. You need to account for each type of
PHP open/close semantic:
<?php
<?
<?=
<script language="php">
And that's just to determine script context. Then you need to know where
a double quote is. Is it starting a string? Is it within HEREDOC? Is it
within a single quoted string, etc. Your best bet is probably to use the
token_get_all() function:
