在我们使用php curl函数时提示Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set…错误，下面我就来介绍碰到此问题要如何来排除问题吧。

如果当你在php中运行 CURLOPT_FOLLOWLOCATION 然后得到php提示错误信息为:

Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set…

错误中提到两个关键safe_mode和 open_basedir,如果你是虚拟主机的没有设置APPCHE的权限是不能通过修改服务器配置来解决问题的,一般来说,服务器配置safe_mode都为off,然后为了一些安全对用户有一些限制,通过设置open_basedir来限制虚拟主机用户的PHP执行文件夹,因此当你使用CURLOPT_FOLLOWLOCATION (php curl函数,深层抓取数据)的时候,一旦有301转向等就会出现文中提到的错误信息.

在查了相关资料后,很快找到了解决办法,http://www.php.net/manual/en/function.curl-setopt.php,这些方法都在php官方帮助里有.

具体做法是在curl语句用不使用curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true),在php函数中自定义一个函数,代码如下:

function curl_redir_exec($ch,$debug="")

{

static $curl_loops = 0;

static $curl_max_loops = 20;

if ($curl_loops++ >= $curl_max_loops)

{

$curl_loops = 0;

return FALSE;

}

curl_setopt($ch, CURLOPT_HEADER, true);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$data = curl_exec($ch);

$debbbb = $data;

list($header, $data) = explode("＼n＼n", $data, 2);

$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

if ($http_code == 301 || $http_code == 302) {

$matches = array();

preg_match('/Location:(.*?)＼n/', $header, $matches);

$url = @parse_url(trim(array_pop($matches)));

//print_r($url);

if (!$url)

{

//couldn't process the url to redirect to

$curl_loops = 0;

return $data;

}

$last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL));

/* if (!$url['scheme'])

$url['scheme'] = $last_url['scheme'];

if (!$url['host'])

$url['host'] = $last_url['host'];

if (!$url['path'])

$url['path'] = $last_url['path'];*/

$new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:'');

curl_setopt($ch, CURLOPT_URL, $new_url);

// debug('Redirecting to', $new_url);

return curl_redir_exec($ch);

} else {//开源软件:Vevb.com

$curl_loops=0;

return $debbbb;

}

}
