Ill probably get attacked viciously for this with pitchforks and machetes,
but I get sick and tired of trying to figure out regular expressions a lot
of times, so I use the following functions... getSingleMatch(),
getMultiMatch(), getSingleMatchBackwards()
function getSingleMatch($start,$end,$content) {
// finds the first match giving a beginning and a part of string that
you want to grab
// eg: to get the title from an html document, you would just use the
command getSingleMatch('<title>','</title>',$html);
$exp = explode($start,$content);
$exp2 = explode($end,$exp[1]);
return $exp2[0];
}
function getMultiMatch($start,$end,$content) {
// finds all the non-embeded matches based on a beginning and ending string
// eg: to get all the h1 tags in an html document, you would use
getMultiMatch('<h1>','</h1>',$html);
$exp = explode($start,$content);
foreach($exp as $pi) {
if(stristr($pi,$end)) {
$ex2 = explode($end,$pi);
$matches[] = $ex2[0];
}
}
return $matches;
}
function getSingleMatchBackwards($start,$end,$content) {
// the same as getSingleMatch except it goes backwards to forwards. This
helps in cases where the
// most distinct delimiter is at the end of your target rather than the
beginning.
$exp = explode($end,$content);
$exp2 = explode($start,$exp[0]);
return $exp2[count($exp2)-1];
}

$pattern= "/[^=]+=([^,]+)/";
preg_match($pattern, $string, $matches);
print_r($matches);
Voila! (Untested for now, I'm pretty drunk so sorry if it ain't workin
out like you want to)
