I wrote code which is doing query and insert inside while loop.

    $getall = mysql_query("SELECT `deviceid`,`uid` FROM  `users` WHERE FIND_IN_SET(`bgroup`,  '".$allbrgou."' ) AND `uid`!='".$from."'");
while($mdata = mysql_fetch_assoc($getall)){
        $newto = $mdata['uid'];

        $result = mysql_query("insert into request(rto,rfrom) values ($newto,$from)");

        $message="You get Request From ".$row['name'] ;
        $url = 'https://android.googleapis.com/gcm/send';

            $fields = array(
                            'registration_ids'  => array($did),
                            'data'              => array( "message" => $message ),
            $headers = array( 
                                'Authorization: key=xxxxxx',
                                'Content-Type: application/json'

            $ch = curl_init();
            curl_setopt( $ch, CURLOPT_URL, $url );
            curl_setopt( $ch, CURLOPT_POST, true );
            curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
            curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
            curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
            $result = curl_exec($ch);


This code on shared hosting took 2 min with just 120 records. Will concatenation and executing insert query fix this performance issue?

  • \$\begingroup\$ Does it work as intended? Have you tested this locally as well to make sure it's not simply your host messing up? \$\endgroup\$ – Mast Apr 19 '16 at 18:57
