  <?php    final class windowsphonepushdelay   {     const immediate=0;     private function __construct(){}  }   class windowsphonepushnotification  {   private $notif_url = '';    function windowsphonepushnotification($notif_url)   {      $this->notif_url = $notif_url;   }   public function push($target,$message,$notif_url)   {     // create toast message    $toastmessage = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" .             "<wp:notification xmlns:wp=\"wpnotification\">" .                "<wp:toast>" .                     "<wp:text1>" . "sendtoast" . "</wp:text1>" .                     "<wp:text2>" . $message . "</wp:text2>" .                     "<wp:param>/receive.xaml?navigatedfrom=toast notification</wp:param>" .                     "</wp:toast> " .             "</wp:notification>";    // create request send      $r = curl_init();      curl_setopt($r, curlopt_url,$notif_url);      curl_setopt($r, curlopt_returntransfer, 1);      curl_setopt($r, curlopt_post, true);      curl_setopt($r, curlopt_header, true);     // add headers      $httpheaders=array('content-type: text/xml; charset=utf-8', 'x-windowsphone-target: toast',                 'accept: application/*', 'x-notificationclass: 2','content-length:'.strlen($toastmessage));   curl_setopt($r, curlopt_httpheader, $httpheaders);    // add message   curl_setopt($r, curlopt_postfields, $toastmessage);    // execute request   $output = curl_exec($r);   curl_close($r);     } }  ?> 

i need output in image below

the wp:param that's part of toast notification's payload should uri. therefore should encoded one. in example you're providing there's space in payload, might causing problems. try formatting this?

  "<wp:param>/receive.xaml?navigatedfrom=toast%20notification</wp:param>" . 

also make sure receive.xaml indeed in root of package.
