php curl 10 seconds timeout (part2)

continue on php curl 10 seconds timeout

code

<?php
$directory = 'http://www.google1.com';  
$returntransfer = true;
$connecttimeout = 10;
timeout = 10; 

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $directory);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, $returntransfer);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $connecttimeout);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);

sleep(10); //wait 10 sec on browser

$execute = curl_exec($ch);
$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
curl_close($ch);

if ($curl_errno > 0) {
    echo "cURL Error ($curl_errno): $curl_error\n";
}
?>

From the above code, my questions is the following:
(1) When I use the sleep(), it will wait 10 seconds on the web page but the CURL_CONNECTTIMEOUT and CURLOPT_TIMEOUT seems nothing happened? Why?
(2) How do I know that the CURLOPT_CONNECTTIMEOUT and CURLOPT_TIMEOUT is set?
