preg_match and delimited strings

I have a string I'd like to have broken into parts using preg_match. I
used a regular expression from the Perl FAQ (http://perlfaq.cpan.org/):
push(@new, $+) while $text =~ m{
"([^\"\\]*(?:\\.[^\"\\]*)*)",? # groups the phrase inside the
quotes
| ([^,]+),?
| ,
}gx;
The idea is that it splits delimited strings respecting the quotes, for
example...
foo, bar, "foo, bar", bar
would end up as
-foo
-bar
-"foo, bar"
-bar
So obviously an explode wont work.
I cant figure out how to convert that piece of perl above into
preg_match. I've copied the string and escaped all the appropriate
charecters however it still wont divide the string show above
properly...
$str = "foo, bar, \"foo, bar\", bar";
$re = "\"([^\\\"\\\\]*(?:\\\\.[^\\\"\\\\]*)*)\",?| ([^,]+),?| ,";
if (preg_match($re, $str, $res)) {
print_r($res);
}
I have other strings that need parsing too (including ones with a
double encapsulator inside the string - eg. 'don''t touch that!'). But
I'm saving those for later.
