Php 在MySQL中插入新行时，如何自动发送android推送通知？

目前我有两个android应用程序共享同一个MySQL数据库。第一个应用程序将向数据库发布数据。第二个应用程序将显示数据库数据。如何在第一个应用将数据发布到数据库后立即自动向第二个应用发送推送通知

知道如何用GCM解决这个问题吗？

将数据发布到数据库后，执行以下代码

$apiKey = "your api key";

        $db_username    = 'root';
        $db_password    = 'root';
        $db_name        = 'gcm001';
        $db_host        = 'localhost';
        $mysqli = new mysqli($db_host, $db_username, $db_password,$db_name);


        if($mysqli->connect_errno > 0){
            die('Unable to connect to database [' . $mysqli->connect_error . ']');
        }   

        //get registration id's from database, whom you want to send notification  ... assuming you have stored registration ids of 2nd app in database
        $query = "SELECT * FROM RegisteredDevices where userid = $userid";

        $result = mysqli_query($mysqli, $query);
        $i=0;
        $data = array();
        while($row   = mysqli_fetch_assoc($result))
        {
            $data[$i] = $row['reg_id'];
            $i++;
        }

        $registrationIDs = array_values($data);
        //print_r($registrationIDs);

        $url = 'https://android.googleapis.com/gcm/send';



        $fields = array(
                        'registration_ids'  => array_values( $registrationIDs ),
                        'data'              => array( "message" => "Your notification message here" ),
                        );

        $headers = array( 
                            'Authorization: key=' . $apiKey,
                            '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 );
         curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );

        // Execute post
        $result = curl_exec($ch);

        // Close connection
        curl_close($ch); 

        echo $result;
