I have decided to post answer for my own question

Now Google introduced FCM

<?php
define('API_ACCESS_KEY','Api key from Fcm add here');
 $fcmUrl = 'https://fcm.googleapis.com/fcm/send';
 $token='235zgagasd634sdgds46436';

    $notification = [
            'title' =>'title',
            'body' => 'body of message.',
            'icon' =>'myIcon', 
            'sound' => 'mySound'
        ];
        $extraNotificationData = ["message" => $notification,"moredata" =>'dd'];

        $fcmNotification = [
            //'registration_ids' => $tokenList, //multple token array
            'to'        => $token, //single token
            'notification' => $notification,
            'data' => $extraNotificationData
        ];

        $headers = [
            'Authorization: key=' . API_ACCESS_KEY,
            'Content-Type: application/json'
        ];


        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,$fcmUrl);
        curl_setopt($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($fcmNotification));
        $result = curl_exec($ch);
        curl_close($ch);


        echo $result;

First of all follow Implementing GCM Client and implement the gcm client in your android app.

For GCM Server in php you can implement it in the following way. Edit your code according to your need like code it for when publishing the post. For more about implementing the GCM Server go to Implementing GCM Server

<?php
    // Replace with the real server API key from Google APIs
    $apiKey = "your api key";

    // Replace with the real client registration IDs
    $registrationIDs = array( "reg id1","reg id2");

    // Message to be sent
    $message = "Your message e.g. the title of post";

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

    $fields = array(
        'registration_ids' => $registrationIDs,
        'data' => array( "message" => $message ),
    );
    $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_POSTFIELDS, json_encode( $fields));

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    // curl_setopt($ch, CURLOPT_POST, true);
    // curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode( $fields));

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

    // Close connection
    curl_close($ch);
    // print the result if you really need to print else neglate thi
    echo $result;
    //print_r($result);
    //var_dump($result);
?>

There is some changes into the code in comment the define(api key line) and put / paste it as my code in php. its working fine comment this :

define('API_ACCESS_KEY','Api key from Fcm add here');

comment or replace this code line :

'Authorization: key=' . API_ACCESS_KEY

//define('API_ACCESS_KEY','Api key from Fcm add here');

$apiKey = 'Api key from Fcm add here';

$fcmUrl = 'https://fcm.googleapis.com/fcm/send';

$token='235zgagasd634sdgds46436';

 $notification = [
        'title' =>'title',
        'body' => 'body of message.',
        'icon' =>'myIcon', 
        'sound' => 'mySound'
    ];
    $extraNotificationData = ["message" => $notification,"moredata" =>'dd'];

    $fcmNotification = [
        //'registration_ids' => $tokenList, //multple token array
        'to'        => $token, //single token
        'notification' => $notification,
        'data' => $extraNotificationData
    ];

    $headers = [
        'Authorization: key=' . $apiKey,
        'Content-Type: application/json'
    ];


    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$fcmUrl);
    curl_setopt($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($fcmNotification));
    $result = curl_exec($ch);
    curl_close($ch);

    echo $result;
