当我在php中使用curl函数时，我总是会收到此错误：
＆＃34;无法连接到www.google.de端口80：连接已超时＆＃34;
如果我在命令行上也这样做：它工作正常......
任何想法为什么？
我的代码：
$ch = curl_init('http://www.google.de');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 1001);
$data = curl_exec($ch);
$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
curl_close($ch);
我的php.ini卷曲设置：
