For those perl fans out there, preg_match_all adds the g (global) flag to the expression. So this:
preg_match('/foo/', $str, $match);
would be like
$str =~ /foo/;
preg_match_all('/foo/', $str, $match);
like
$str =~ /foo/g;

p.s. - anyone coming from Perl to PHP can get a little hung up on the preg_* functions...

preg_match stops after the first match.
preg_match_all gets *all* the matches.
E.g. If you have a string -> $str = "foofoo";
preg_match('/foo/', $str, $match); -> $match will have an array with one
"foo".
preg_match_all('/foo/', $str, $match); -> $match will have an array with
two "foo".
Thats basically it.
