Curl_setopt ($ch, CURLOPT_URL, $url)
Curl_setopt ($ch, CURLOPT_POST, 1)
Curl_setopt ($ch, CURLOPT_HEADER, 0)
Curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1)
Curl_setopt ($ch, CURLOPT_POSTFIELDS, $data)
$return = curl_exec ($ch)
Curl_close ($ch)
$regex4= "/. *? / ism"
If (preg_match_all ($regex4, $return, $matches)) {
Print_r ($matches)
} else {
Echo'0'
