php curl_exec cannot get urlencoded link's content
<p>The link is: <a href="http://web.centanet.com/m/Property/%E6%B5%B7%E6%80%A1%E5%8D%8A%E5%B3%B64%E6%9C%9F%E5%BE%A1%E5%BA%AD%E5%9C%92%E5%BE%A1%E6%9E%97%E5%B1%85%2833%E5%BA%A7%29/TIB981-0813" rel="nofollow">this</a></p>

<p>It is ok to open in my browser. However, when i use the following php script to get the content, it shows: Runtime Error. Any ideas? Thanks.</p>

<pre><code>$html = get_url_contents('http://web.centanet.com/m/Property/%E6%B5%B7%E6%80%A1%E5%8D%8A%E5%B3%B64%E6%9C%9F%E5%BE%A1%E5%BA%AD%E5%9C%92%E5%BE%A1%E6%9E%97%E5%B1%85%2833%E5%BA%A7%29/TIB981-0813');
echo $html;
exit;

function get_url_contents($url){
       $crl = curl_init();
       curl_setopt ($crl, CURLOPT_URL,$url);
       $ret = curl_exec($crl);
       curl_close($crl);
       return $ret;
}
</code></pre>
