调用php脚本作为插入数据库的新记录

我只是在创建一个用于推送通知的web服务。I这是我的代码-

<?php

// gcm api KEY FOR PUSH NOTIFICATION
define( 'API_ACCESS_KEY', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ123456' );
// CONNECT DB
$dbhandle = mysql_connect("localhost", "admin", "admin") or die(mysql_error()) ; 
$selected =  mysql_select_db("bdname" ,$dbhandle) or die(mysql_error()); 
$query4=mysql_query("SELECT * FROM `table_name` ORDER BY id DESC LIMIT 0,1");
$row1=mysql_fetch_array($query4);
// static gcm registration id
$reg = 'APA91bF-A97EurJz7IlGFD85cBIWGPCJv7UhV1j19sp6nKEH-9He1GOZQ9ZPegqYmVw3q2OA-_XPpePQckr5o97s9wTTbzYjornXCOqcR3jmN1t1aHV8i4CfRZOWuBDXTixzA3JDnzleHVY3xCtHev8tG90ife05Pw';
$registrationIds = array($reg);
$title=$row1['title'];
$number=$row1['number'];
$id=$row1['id'];
$created_at=$row1['created_at'];
$mes1 = $id .',' . $title . ',' . $number .',' . $created_at;
$message = str_replace('""','',$mes1);
$mes = $message;
$message = array("price" => $mes);
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
            'registration_ids' => $registrationIds,
            'data' => $message,
        );
        $headers = array(
            'Authorization: key=' . API_ACCESS_KEY,
            'Content-Type: application/json'
        );
        // Open connection
        $ch = curl_init();
// Set the url, number of POST vars, POST data
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        // Disabling SSL Certificate support temporarly
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

// Execute post
        $result = curl_exec($ch);
        if ($result === FALSE) {
            die('Curl failed: ' . curl_error($ch));
        }
        // Close connection
        curl_close($ch);
        echo $result;
//}
mysql_free_result($query4);

mysql_close($dbhandle);
?>

我只想如果有任何新行插入到表中，这个脚本将自动调用并发送给定gcm注册id的通知。我该怎么做呢。有没有php函数可以做到这一点？？请帮忙。提前谢谢。
