using fsockopen() with login/different port required HTTP/FTP servers

[Dedix]

Hi there all

However I have opened a similar topic, but this one's purpose is sharing all of our experiences, tutorials, etc. with fsockopen() function...
It seems it's a pretty tricky function...:-)

But i also have an exact problem. I want a php script that can check file sizes on both FTP and HTTP remote servers even if they require login/pass or diffrent port than default.

I have this code:

error_reporting(E_ALL);

$kb = 1024;
$mb = 1024 * $kb;
$gb = 1024 * $mb;
$tb = 1024 * $gb;

if (!isset($f)) {
$fileurl = "http://digitalspacenet.tucows.com/files5/12wash.exe";
} else {
$fileurl = $f;
}
$pu = @parse_url($fileurl);
$filename = basename($fileurl);

$domain = $pu['host'];
$file =   $pu['path'];
$host =   $pu['host'];
$http = "GET ".$file." HTTP/1.0\r\nHost: ".$host."\r\n\r\n"; 
$fp = fsockopen ($domain, 80, $errno, $errstr, 30); 

if (!$fp) {
   echo "$errstr ($errno)<br>\n";
} 
else {
    fputs ($fp, $http);
    while (!feof($fp)){
        $chunk= fgets ($fp,128);
        if (strpos($chunk, "ength:"))
    { 
       $size = explode (':', $chunk);

  if($size[1] < $kb) {
       $s = $size[1]." B";
   }
   else if($size[1] < $mb) {
      $s = round($size[1]/$kb,2)." KB";
   }
   else if($size[1] < $gb) {
       $s = round($size[1]/$mb,2)." MB";
  }
   else if($size[1] < $tb) {
       $s = round($size[1]/$gb,2)." GB";
   }
   else {
      $s = round($size[1]/$tb,2)." TB";
   }

   echo "A(z) $filename fájl mérete: $s";
   break;
}
 }
fclose ($fp);
}

This works with the following url formats:

http://www.example.com/files/file.zip
http://example.com/files/file.zip
[url]ftp://ftp.example.com/files/file.zip[/url]
[url]ftp://example.com/files/file.zip[/url]

but doesn't work with these formats:

[url]http://user:[e-mail]/files/file.zip[/url]
http://user:[e-mail]/files/file.zip
[url]ftp://user:[e-mail]/files/file.zip[/url]
[url]ftp://user:[e-mail]/files/file.zip[/url]
[url]ftp://user:[e-mail]:666/files/file.zip[/url]
[url]ftp://user:[e-mail]:666/files/file.zip[/url]

So, my primary question is how can i get this code to check filesizes on both HTTP and FTP servers even if they are required to use user/pass and/or different port than default?

Any help would be appreciated!
Includes docs, tutorials, sample codes, everything about fsockopen() function!
