$htmlstr = get_html("http://shop.m.taobao.com/shop/coupon.htm?activityId=95504434dcf441ba8988ccaf73d66917&sellerId=2301680205");
$start = strpos($htmlstr, "<span class=\"rest\">");
$end = strpos($htmlstr, "</span>", $start);
$surplusnum = substr($htmlstr,$start, $end-$start);用curl获取页面某个class的 上面这段代码url是填的链接 $surplusnum可以获取
但是如果是下面这段代码url是字符串 $surplusnum就获取不了，$vurl打印出来是有链接的
麻烦帮忙看下这是什么原因$htmlstr = get_html($vurl);
$start = strpos($htmlstr, "<span class=\"rest\">");
$end = strpos($htmlstr, "</span>", $start);
$surplusnum = substr($htmlstr,$start, $end-$start);
假定读出到 $url
你 echo base64_encode($url); 贴出结果
输出的aHR0cDovL3Nob3AubS50YW9iYW8uY29tL3Nob3AvY291cG9uLmh0bT9hY3Rpdml0eUlkPTYxZjY2MDE2MjI2MDRlMTlhMWU2ZjhmZDEzNmJjYzM5JmFtcDtzZWxsZXJJZD0yMjYyNzA1Mzg3

他用 js 进行了跳转，所以不是你的代码有问题，而是你的方案有问题
