Answer 1

query($q) ;
if ($result1->num_rows > 0) {

$response["users"] = array();

while ($row = $result1->fetch_array(MYSQLI_BOTH)) {
    $user = array();
    $registrationIds = array($row[0]);


    $msg = array
    (
    'message'   => 'hieee',
    'title'     => 'Blood Bank',
    'subtitle'  => 'This is a subtitle. subtitle',
    'tickerText'    => 'Ticker text here...Ticker text here...Ticker text here',
    'vibrate'   => 1,
    'sound'     => 1,
    'largeIcon' => 'large_icon',
    'smallIcon' => 'small_icon'
    );

    $fields = array
    (
    'registration_ids'  => $registrationIds,
    'data'          => $msg
    );

    $headers = array
    (
    'Authorization: key=' . API_ACCESS_KEY,
    'Content-Type: application/json'
    );

    $ch = curl_init();
    curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
    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 ) );
    $result = curl_exec($ch );
    curl_close( $ch );

    echo $result;
    }
} 
else {
    $response["success"] = 0;
    $response["message"] = "No users found";
