The code is as follows:

$ Ch = curl_init ();
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 = "/

.*? <\/P>/ism ";
If (preg_match_all ($ regex4, $ return, $ matches )){
Print_r ($ matches );
} Else {
Echo '0 ';
}
