Examples

Example #1 curl_getinfo() example

 <?php
// 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);
?>

Notes

Note:
Information gathered by this function is kept if the handle is re-used. This means that unless a statistic is overridden internally by this function, the previous info is returned.
