Global file inspection
Is it possible to get data like filesize or file_exist from files over the net?

Code: Select all
<?php
<?php
/*
* (mixed)remote_filesize($uri)
* returns the size of a remote stream in bytes or
* the string 'unknmown'
*/
function remote_filesize($uri)
{
// 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);
$okay = curl_exec($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();
// 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';
}
return $size;
}
?>

For Windows users, note that when the manual says "this function will not work on remote files", that also includes other drive partitions on the same computer.
