使用这个

                $data = array('post_id'=>'12345','title'=>'A Blog post', 'message' =>'test msg');

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

许多教程都过时了，甚至当前的代码都没有考虑设备注册id何时更新或设备取消注册。如果不检查这些项目，最终将导致无法接收消息的问题。http://forum.loungekatt.com/viewtopic.php?t=63#p181

实际上，我现在在Zend_Mobile树的一个分支中工作:https://github.com/mwillbanks/Zend_Mobile/tree/feature/gcm

这将与ZF 1.12一起发布，但是，它应该会给你一些关于如何做到这一点的很好的例子。

这里有一个关于它如何工作的快速演示....

<?php
require_once 'Zend/Mobile/Push/Gcm.php';
require_once 'Zend/Mobile/Push/Message/Gcm.php';

$message = new Zend_Mobile_Push_Message_Gcm();
$message->setId(time());
$message->addToken('ABCDEF0123456789');
$message->setData(array(
    'foo' => 'bar',
    'bar' => 'foo',
));

$gcm = new Zend_Mobile_Push_Gcm();
$gcm->setApiKey('MYAPIKEY');

$response = false;

try {
    $response = $gcm->send($message);
} catch (Zend_Mobile_Push_Exception $e) {
    // all other exceptions only require action to be sent or implementation of exponential backoff.
    die($e->getMessage());
}

// handle all errors and registration_id's
foreach ($response->getResults() as $k => $v) {
    if ($v['registration_id']) {
        printf("%s has a new registration id of: %s\r\n", $k, $v['registration_id']);
    }
    if ($v['error']) {
        printf("%s had an error of: %s\r\n", $k, $v['error']);
    }
    if ($v['message_id']) {
        printf("%s was successfully sent the message, message id is: %s", $k, $v['message_id']);
    }
}

使用这个

 function pnstest(){

                $data = array('post_id'=>'12345','title'=>'A Blog post', 'message' =>'test msg');

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

                $server_key = 'AIzaSyDVpDdS7EyNgMUpoZV6sI2p-cG';

                $target ='fO3JGJw4CXI:APA91bFKvHv8wzZ05w2JQSor6D8lFvEGE_jHZGDAKzFmKWc73LABnumtRosWuJx--I4SoyF1XQ4w01P77MKft33grAPhA8g-wuBPZTgmgttaC9U4S3uCHjdDn5c3YHAnBF3H';

                $fields = array();
                $fields['data'] = $data;
                if(is_array($target)){
                    $fields['registration_ids'] = $target;
                }else{
                    $fields['to'] = $target;
                }

                //header with content_type api key
                $headers = array(
                    'Content-Type:application/json',
                  'Authorization:key='.$server_key
                );

                $ch = curl_init();
                curl_setopt($ch, CURLOPT_URL, $url);
                curl_setopt($ch, CURLOPT_POST, true);
                curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
                curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
                curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
                curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
                $result = curl_exec($ch);
                if ($result === FALSE) {
                    die('FCM Send Error: ' . curl_error($ch));
                }
                curl_close($ch);
                return $result;

}

这很容易做到。Elad Nava放在这里的页面上的cURL代码是有效的。Elad评论了他收到的错误。

描述在为该收件人处理消息时发生的错误的字符串。可能的值与上表中记录的值相同，再加上“Unavailable”(意味着GCM服务器繁忙，无法为特定的收件人处理消息，因此可以重试)。

我已经得到了一个服务设置，似乎已经工作(ish)，到目前为止，我已经回来的都是不可用的回报从谷歌。这种情况很可能很快就会改变。

要回答这个问题，请使用PHP，确保Zend框架在您的include路径中，并使用以下代码:

<?php
    ini_set('display_errors',1);
    include"Zend/Loader/Autoloader.php";
    Zend_Loader_Autoloader::getInstance();

    $url = 'https://android.googleapis.com/gcm/send';
    $serverApiKey = "YOUR API KEY AS GENERATED IN API CONSOLE";
    $reg = "DEVICE REGISTRATION ID";

    $data = array(
            'registration_ids' => array($reg),
            'data' => array('yourname' => 'Joe Bloggs')
    );

    print(json_encode($data));

    $client = new Zend_Http_Client($url);
    $client->setMethod('POST');
    $client->setHeaders(array("Content-Type" => "application/json", "Authorization" => "key=" . $serverApiKey));
    $client->setRawData(json_encode($data));
    $request = $client->request('POST');
    $body = $request->getBody();
    $headers = $request->getHeaders();
    print("<xmp>");
    var_dump($body);
    var_dump($headers);

结果出来了。一个在Zend Framework PHP中使用google新GCM的工作示例(很快就会工作)。

你可以在packagist上使用这个PHP库:

https://github.com/CoreProc/gcm-php

安装后，你可以这样做:

$gcmClient = new GcmClient('your-gcm-api-key-here');

$message = new Message($gcmClient);

$message->addRegistrationId('xxxxxxxxxx');
$message->setData([
    'title' => 'Sample Push Notification',
    'message' => 'This is a test push notification using Google Cloud Messaging'
]);

try {

    $response = $message->send();

    // The send() method returns a Response object
    print_r($response);

} catch (Exception $exception) {

    echo 'uh-oh: ' . $exception->getMessage();

}
