If the OP means PHP's curl, you can look at this code:
$file_sizeofurl =
a_array['Content-Length'];
--------------------2. Use curl to get the size of a remote file
What if the server forbids get_headers?
Use another method, with curl.
I've always felt that curl is like a virtual user, able to imitate anything.
Below is a function from a foreigner
Please note
echo '
head-->'.$head.'<----end
';
I added this line, so I could see exactly what the header contains
function
remote_filesize($uri,$user='',$pw='')
{
// start output
buffering
ob_start();
// initialize curl with given uri
$ch =
curl_init($uri);
// make sure we get the header
curl_setopt($ch,
CURLOPT_HEADER, 1);
// make it a http HEAD request
curl_setopt($ch,
CURLOPT_NOBODY, 1);
// if auth is needed, do it here
if (!empty($user)
&& !empty($pw))
{
$headers = array('Authorization: Basic ' .
base64_encode($user.':'.$pw));
curl_setopt($ch, CURLOPT_HTTPHEADER,
$headers);
}
$okay = curl_exec($ch);
curl_close($ch);
// get the
output buffer
$head = ob_get_contents();
// clean the output buffer and
return to previous
// buffer settings
ob_end_clean();
echo '
head-->'.$head.'<----end
';
// gets you the numeric value from the Content-Length
// field in the http header
$regex = '/Content-Length:s([0-9].+?)s/';
$count = preg_match($regex, $head, $matches);
// if there was a Content-Length field, its value
// will now be in $matches[1]
if (isset($matches[1]))
{
$size = $matches[1];
}
else
{
$size = 'unknown';
}
//$last=round($size/(1024*1024),3);
//return $last.' MB';
return $size;
}
