第三、调用短信服务器短信接口
笔者整理的页面是yanzhengma.php(具体根据服务商提供信息)
$v)
{
  $o.="$k=".$v.’&’;
}
$post_data=substr($o,0,-1);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //如果需要将结果直接返回到变量里，那加上这句。
$result = curl_exec($ch);
?>
第四：提交表单信息时对短信验证码验证
//手机验证码开始
        session_start();
              $svalitel = $_SESSION[’mobilecode’];
              $vdcodetel = empty($vdcodetel) ? ’’ : strtolower(trim($vdcodetel));
            if(strtolower($vdcodetel)!=$svalitel || $svalitel==’’)
            {
                ResetVdValue();
                            //echo "Pageviews=".$vdcodetel;
                            ShowMsg("手机验证码错误！", ’-1’);
                exit();
