The specific code is as follows:

$str_tmp  = DAdmin_Utils::gbkStrSplit(“短信内容”, 700);//内容过长返回的是一个截取内容后的数组  700指的是截取的长度
    $total = count($str_tmp);
    $num  = 1;
    foreach($str_tmp as $str)
    {
      if($total > 1)
      {
       $str = $str . "{$num}/{$total}";
       $num ++;
      }
      $sign = strtoupper(md5($key.$pMobile.$str.$ip));
      $url = "短信地址?from=37&sgin=".$sign."&tel=".$pMobile."&msg=".$str;
      $ret = file_get_contents($url);
      $result = json_decode($ret,true);
    }
//发送短信方法
function gbkStrSplit($string, $len = 1)
  {
    $length = strlen($string);//获取长度，汉字占三个字节
    $retstr = '';
    $retArr = array();
    for ($i = 0; $i < $length; $i++) {
      $retstr .= ord($string[$i]) > 127 ? $string[$i] . $string[++$i] : $string[$i];
      $len_tmp = strlen($retstr);
      if ($len_tmp >= $len) {
        $retArr[] = $retstr;
        $retstr = &#39;&#39;;
      }
    }
    if ($retstr != &#39;&#39;) {
      $retArr[] = $retstr;
    }
    return $retArr;
  }
