$opts = Array (' http ' =>array (' Request_fulluri ' =>true));
$context = Stream_context_create ($opts);
$content = File_get_contents ($url, False, $context);

Stream_context_create () is used to set the timeout time:

Copy Code code as follows:

$opts = Array (
' HTTP ' =>array (
' Method ' => ' get ',
' Timeout ' =>60,
)
);
$context = Stream_context_create ($opts);
$html =file_get_contents (' http://www.jb51.net ', false, $context);
