handle file_get_contents timeout including dns lookup time

Dear all i'm trying to handle a max timeout into a file_get_contents request, this is my code: ******* client.php ******* placed on http://test.foo.com/client.php <?php ini_set('default_socket_timeout',10); $ctx = stream_context_create(array('http' => array('timeout' => 10))); $data = file_get_contents("http://www.foo.com/server.php",0,$ctx); if(!data){ die("error during page request"); }else{ echo "OK"; echo $data; } ?> ******* server.php ******* placed on www.foo.com at http://www.foo.com/server.php <?php sleep(15); echo "OK"; ?> i've noticed that in a standard scenario if i call http://test.foo.com/client.php all works properly and the timeout is handled correctly. But, if i'm experiencing dns lookup problems, the timeout setting is ignored by file_get_contents, or more probably the socket isn't yet estabilished so the counter for timeout doesn't start. I've been able to reproduce this problem on a linux server dropping incoming packets of DNS with this command: (be careful, it will disable you ability to resolve all dns address!): * iptables -A INPUT -p udp --sport 53 -j DROP * iptables -A INPUT -p tcp --sport 53 -j DROP So, the question is: is possible to have a timeout check that includes also dns resolution time? Thanks to all in advance
