SMS button

Hi

I have made an SMS handle button

Below is the code, but the button stucks on the "Please wait message", no error, no result
Client after
params["txt"] = document.getElementById('sms_form').value;

ctrl.setMessage("Please wait...");
SERVER
global $dal;

$dal_TableName = $dal->Table("tal_school_job");

$sms_list = "";

foreach(@$keys as $keyblock)

{

$arr=explode("&",refine($keyblock["ID"]));

if(count($arr)<1)

continue;

$arr2=array();

$arr2["ID"]=urldecode(@$arr[0]);

$where = KeyWhere($arr2);

$rstmp = $dal_TableName->Query($where,"");

$datatmp=db_fetch_array($rstmp );

if ($datatmp["Parent_Contact"])

$sms_list.=$datatmp["Parent_Contact"].",";

}

if ($sms_list)

$sms_list=substr($sms_list,0,-1);
echo $sms_list;

if ($text)

$text.=", ";

$text.=$params["txt"];

$mobile=$sms_list;

//////////

$username = "xxxxxxxxxxx";

$password = "xxxxx";

$sendername = "XXXX";

$message= urlencode($text);

if ($username && $password && $to && $message) {

$data = "?username=$username&password=$password&sendername=$sendername&mobile=$mobile&message=$message&routetype=0";

$data = urlencode($data);

$file = fopen('clients.xxxxxxx.com/sms_api/sendsms.php'.$data,'r';);

$output = fread($file,1024);

fclose($file);

echo $output;

}

///////////
CLIENT AFTER

// Put your code here.

var message = result["txt"] + " !!!";

ctrl.setMessage(message);
Below is the http API of the sms service.

<?php
$request = "";

$param["username"] = "xxxx"; // YOUR LOGIN USERNAME

$param["password"] = "yyyy"; // YOUR LOGIN PASSWORD

$param["sendername"] = "WEBSMS"; // YOUR SENDERID

$param["mobile"] = "$mobile"; // Receiver Mobile NO

$param["routetype"] = "1";

$param["message"] = "Hi Customer, Thanks for using our service. -- www.xxxxxxxx.com";; // Receiver MSG
foreach($param as $key=>$val){$request.= $key."=".urlencode($val); $request.= "&";}

$request = substr($request, 0, strlen($request)-1);
$host = "clients.xxxxx.com";

$script = "/sms_api/sendsms.php";

$request_length = strlen($request);

$method = "POST";

if ($method == "GET"){$script .= "?$request";}
$header = "$method $script HTTP/1.1\r\n";

$header .= "Host: $host\r\n";

$header .= "Content-Type: application/x-www-form-urlencoded\r\n";

$header .= "Content-Length: $request_length\r\n";

$header .= "Connection: close\r\n\r\n";

$header .= "$request\r\n";
$socket = @fsockopen($host, 80, $errno, $errstr);

if ($socket)

{

fputs($socket, $header);

while(!feof($socket)){$output[] = fgets($socket);}

fclose($socket);

}
?>
