How to check file size in via Internet? The sample below is my code that does not work
echo filesize('http://localhost/wordpress-3.1.2.zip');
echo filesize('http://www.wordpress.com/wordpress-3.1.2.zip');

Answer 1

The filesize function is used to get size of files stored locally.* For remote files you must find other solution, for example:
<?php
function getSizeFile($url) {
if (substr($url,0,4)=='http') {
$x = array_change_key_case(get_headers($url, 1),CASE_LOWER);
if ( strcasecmp($x[0], 'HTTP/1.1 200 OK') != 0 ) { $x = $x['content-length'][1]; }
else { $x = $x['content-length']; }
}
else { $x = #filesize($url); }
return $x;
}
?>

*Well, to be honest since PHP 5 there are some wrappers for file functions, see here:

You can find a lot more examples, even here on SO, this should satisfy your needs: PHP: Remote file size without downloading file
Try to use search function before asking question next time!

try this function
<?php
function remotefsize($url) {
$sch = parse_url($url, PHP_URL_SCHEME);
if (($sch != "http") && ($sch != "https") && ($sch != "ftp") && ($sch != "ftps")) {
return false;
}
if (($sch == "http") || ($sch == "https")) {
$headers = get_headers($url, 1);
if ((!array_key_exists("Content-Length", $headers))) { return false; }
return $headers["Content-Length"];
}
if (($sch == "ftp") || ($sch == "ftps")) {
$server = parse_url($url, PHP_URL_HOST);
$port = parse_url($url, PHP_URL_PORT);
$path = parse_url($url, PHP_URL_PATH);
$user = parse_url($url, PHP_URL_USER);
$pass = parse_url($url, PHP_URL_PASS);
if ((!$server) || (!$path)) { return false; }
if (!$port) { $port = 21; }
if (!$user) { $user = "anonymous"; }
if (!$pass) { $pass = "phpos#"; }
switch ($sch) {
case "ftp":
$ftpid = ftp_connect($server, $port);
break;
case "ftps":
$ftpid = ftp_ssl_connect($server, $port);
break;
}
if (!$ftpid) { return false; }
$login = ftp_login($ftpid, $user, $pass);
if (!$login) { return false; }
$ftpsize = ftp_size($ftpid, $path);
ftp_close($ftpid);
if ($ftpsize == -1) { return false; }
return $ftpsize;
}
}
?>

I think that's probably not possible. The best way is to download the file via file_get_contents and then use filesize over the file. You can later delete the file too!
