Sending Push notification to android Using PHP :curl failed

Question

I am trying to send push notification some android devices using the registration ids which is stored in database table.

Here is my code

  //message and title for push notification
  $msg=$_POST['message'];
  $title=$_POST['title'];
  $result=$connect->prepare("SELECT `push_id` FROM `user_devices`");
  $result->execute();
  //get registration id's
  $ids=$result->fetchAll(PDO::FETCH_COLUMN);
  $key="XXXXX";
  $url = 'https://android.googleapis.com/gcm/send';
  $fields = array(
                'registration_ids'  =>$ids,
                'data'              => array( "message" =>$msg,"title"=>$title,"soundname"=>"beep.wav" ),
                );
  $headers = array(
                    'Authorization: key=' . $key,
                    '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 ) );
  $res = curl_exec($ch);
  if($res === false)
     echo 'Curl failed ' .curl_error();
  }

I am getting curl Failed error message but didn't see anything from curl_error().

UPDATE

I am running this script from windows server which is hosted in azure cloud service. Now i am run this from linux based server its works fine,but it didnt work in windows server.

You are probably getting error due to SSL (in your url https) issue. You have to configure your curl to handle secured request. You can find a hints from here: Configuring cURL for SSL

You are not getting the error msg because you need to print it like below:

echo 'Curl failed ' .curl_error($ch); // you are missing $ch here

Alternately you can run your curl with verbose enabled to see the things happening with your curl request!

curl_setopt( $ch, CURLOPT_VERBOSE, true );

It was the problem of My SSL Certificate.

Solved using one line code curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); is placed in after curl_init.

NOTE

This is a temporary solution.Actual way is generate an SSl certificate.
