I want to download a image from a remote server only if it is not older than 2 days. I have the constructing as below now. Is this right? I want to now the last_modified data first before downloading.

$ch = curl_init($file_source); // the file we are downloading curl_setopt($ch, CURLOPT_TIMEOUT, 20); curl_setopt($ch, CURLOPT_FILE, $wh); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_FILETIME, true); curl_exec($ch); $headers = curl_getinfo($ch); $last_modified = $headers['filetime'];

if ($last_modified != -1) { // unknown echo date("Y-m-d", $last_modified); //etc }

curl_close($ch); fclose($wh);
