예제들 소스

// Create a curl handle
$ch = curl_init('http://www.yahoo.com/');

// Execute
curl_exec($ch);

// Check if any error occured
if(!curl_errno($ch))
{
 $info = curl_getinfo($ch);

 echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url'];
}

// Close handle
curl_close($ch);

결과..
Took 0.554 seconds to send a request to http://www.yahoo.com/
