使用php curl函数时提示Warning: curl_setopt() [function.curl-setopt]: CURLO…错误该怎么解决

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.gaodaima.com/php-weizijiaocheng-362563.html,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 {$curl_loops=0;return $debbbb;}}

函数定义好后,curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true)这条语句替换为curl_redir_exec($ch)

这样以后,我想你的PHP文件应该不会提示错误了,关于这段代码,在提供PHP官方连接用可以找到.

php官方的代码如下
