php 中 curl_setopt 问题，模拟提交网站

Question

<?php

$url = "http://www.directoryws.com/submit.php";

$data = array();
$data['LINK_TYPE'] ="free";
$data['TITLE'] ="isreanod";
$data['URL'] ="http://www.baidu.com";
$data['DESCRIPTION'] ="uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuiii";
$data['OWNER_NAME'] ="reanod";
$data['OWNER_EMAIL'] ="[e-mail]";
$data['CATEGORY_ID'] ="2";
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

// 自动跟随跳转
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, 1);

$return = curl_exec($ch);// 执行操作
if (curl_errno($ch)) {
echo 'Errno'.curl_error($ch);//捕抓异常
}
curl_close($ch); // 关闭CURL会话

var_dump($return);// 返回数据

为啥就是不成功呢？？？

php的curl模块开启了吗？
