Friends I have debugging my code and when I hit no. 1 id size is given but in no.2 I did'nt get any size I think thats why 2nd link type not downloaded. here is my function of getting size .
function get_size($url) {
$my_ch = curl_init();
curl_setopt($my_ch, CURLOPT_URL,$url);
curl_setopt($my_ch, CURLOPT_HEADER, true);
curl_setopt($my_ch, CURLOPT_NOBODY, true);
curl_setopt($my_ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($my_ch, CURLOPT_TIMEOUT, 10);
$r = curl_exec($my_ch);
foreach(explode("
", $r) as $header) {
if(strpos($header, 'Content-Length:') === 0) {
return trim(substr($header,16));
}
}
return '';
}
