抓取上面连接的  HTML     用file_get_contents() 测试没成功    怎么回事啊?
------解决思路----------------------
file_get_contents() 成功了呀

<br /><?php <br />	$url="http://detail.tmall.com/item.htm?spm=a230r.1.0.0.MlI5e4&id=40364502055&ad_id=&am_id=&cm_id=140105335569ed55e27b&pm_id";<br />	$content = getcurl($url);<br />	echo $content;<br /><br />	<br />    function getcurl($url){<br />		$ch = curl_init(); <br />		curl_setopt($ch, CURLOPT_URL, $url);<br />		curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);<br />		curl_setopt($ch, CURLOPT_FOLLOWLOCATION,true);<br />		curl_setopt($ch, CURLOPT_MAXREDIRS,20);<br />		$file_contents = curl_exec($ch);<br />		return $file_contents;<br />		curl_close($ch);<br />    }<br />?><br />

其中curl_setopt($ch, CURLOPT_FOLLOWLOCATION,true);设置比较重要,可以用来跟随天猫的重定向页面。
