求助php无法抓取网页,问了几个人都没解决

<br />$url="http://110.75.65.8/search_turn_page_iphone.htm?sort=&q=liz claiborne&page=1&showMode=list";<br />echo Post($url);<br /><br />function Post($url, $post = null)//请求的网页<br />{<br />$context = array();<br /><br />	if (is_array($post))<br />	{<br />		ksort($post);<br />		<br />		$context['http'] = array<br />		(<br />		<br />		'timeout'=>60,<br />		'method' => 'POST',<br />		'header'=>">Accept-language: en/r/n",<br />		'content' => http_build_query($post, '', '&'),<br />		);<br />	}<br /><br />return file_get_contents($url, false, stream_context_create($context));<br />}<br />
