match php code

Hello to everybody, this is my first post...

First of all sorry for my english, I'm Italian ;)

I'm Trying to match php code, by preg functions of php, and
I've some
problems.

In Fact is simply to match something like this:
<?php
 echo "hello world;
?>

but is more complicated, for me, to match this one:
<?php
 print "hello?> w\"orld";
 echo "Hello ?> world";
?>

This last snippet is valid php code.
So I've tried something like:

/(<\?php|<\?=|<\?)(.*?(?:('|")(?:(?:\\
3|[^\3])*?\3)*?.*?)*?)(\?>)/s

or

/(<\?php|<\?=|<\?)(.*?(?:('|\")(?:\\\
3|[^\3])*?\3)+.*?)(\?>)/s

nothing to do...

Any ideas?

I'm guessing your problem is with the quotes -- you could
use this to
capture the string with the escaped quote in it:
".+?(?<!\\)"

To capture the entire snippet you could use this regex:

But that one isn't smart enough to know whether it's
double or single
quotes, that would take a little more tweaking and I'm a
bit in a hurry 
-- basically just capture the first double or single quote
into a
backreference then reference it at the close of the quotes
to make sure
you're matching them.  In this, nothing is pulled into
backreferences, it's
just a quick regex to show how you could capture it.

Also keep in mind that when plugging regex into php, you're
going to have
to double up on backspaces -- so \\ would become \\\\
-- \r would become
\\r etc.
