PHP 做群发短信（短信接口连接问题）

//首先写个方法
function sendSMS($http,$username,$password,$sendmobile,$send_content){
    $httpurl = $http;
    $data = array
     (
     'USERNAME'=>$username,     //用户账号
     'PASSWORD'=>$password, //用户密码
     'MOBILE'=>$sendmobile,    //号码
     'CONTENT'=> mb_convert_encoding($send_content,'GB2312','UTF-8'), //内容
     );
    $re= $this->postSMS($httpurl,$data);   //POST方式提交
    if(trim($re)>0)
    {
     return "success";
    }
    else 
   {
     return "error";
    }
 }
  function postSMS($httpurl,$data=''){
  $row = parse_url($httpurl);
  $host = $row['host'];
  $port = isset($row['port']) ? $row['port']:80;
  $file = $row['path'];
  $post = '';
  while (list($k,$v) = each($data)) 
 {
   $post .= ($k)."=".($v)."&"; 
  }
  $post = substr($post,0 ,-1);
  $len = strlen($post);
  
  $fp = @fsockopen( $host ,$port, $errno, $errstr, 10);
  if (!$fp) {
   return "$errstr ($errno)\n";
   }else {
   $receive = '';
   $out = "POST $file HTTP/1.1\r\n";
   $out .= "Host: $host\r\n";

PHP处理页面

  $httpurl = $sms_config['httpurl'];
  $username = $sms_config['username'];
  $password = $sms_config['password'];
  $balance_info = $balance->GetBlanceInfo($uid);
  $balance_sy = $balance_info['balance_info']-$balance_info['rate'];
  $rate = $balance_info['rate'];
  if($balance_sy > $rate){
