想用PHP抓取某网站库存数据

想抓取这个网站的剩余库存数量
http://www.beibei.com/detail/105272.html
使用fopen()，然后再读取的源代码中，显示的库存量为0，查了资料说需要伪装HTTP，不知道怎么弄，在线等大牛~~~

回复讨论(解决方案)

file_get_contents(); 获取源码后再用正则过滤。

版主，里面的库存量用这个方法抓取到的是- 空的·····

已解出：

<?php// 获取页面内容$content = file_get_contents('http://www.beibei.com/detail/105272.html');// 获取hxcsrfpreg_match('/g.__t__ = \"(.*)\";/U', $content, $matches);$hxcsrf = $matches[1];// 获取idpreg_match('/pageData.encryptId = \'(.*)\';/U', $content, $matches);$id = $matches[1];// post 到 api 获取sku$skuapi = 'http://www.beibei.com/item/detail/get_sku.html';$postdata  =  http_build_query (    array(         'hxcsrf' => $hxcsrf,         'id' => $id     ));$opts  = array( 'http'  =>    array(         'method'   =>  'POST' ,         'header'   =>  'Content-type: application/x-www-form-urlencoded' ,         'content'  =>  $postdata     ));$context = stream_context_create($opts);$sku = file_get_contents($skuapi, false, $context);$result = json_decode($sku, true);echo '<meta http-equiv="content-type" content="text/html;charset=utf-8">';echo '<pre class="prettyprint linenums">';print_r($result);echo '
