Filesize function help needed

[refiking]

I am trying to get the filesize of a file on another server.  Do I have to log into the account via ftp_connect to get this?  Please help.

 

echo filesize($file);

If it's listed here shouldn't be a problem:

Are you getting an error?

yeah, I had no problem with fopen, but it's still not displaying the filesize when I wrote filesize($file)

hmm..you shouldn't have to login...for example this right here should work:

 

echo filesize("http://www.phpfreaks.com/forums/index.php");

 

But then again I'm not 100% sure on that, just try it out and see.

If it isnt working, try this function. It's served me well.

 

function getFileSize($url) {
    if (substr($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;
}

Here's what that returned:

 

Warning: filesize() [function.filesize]: stat failed for http://www.phpfreaks.com/forums/index.php in XXX on line 4

            $x = $x['content-length'];
        }
    } else {
        $x = @filesize($url);
    }
    return $x;
}

 

I entered getFileSize("http://www.phpfreaks.com/forums/index.php"); and it didn't return anything.  Did I not use it correctly?

Strange. That function works fine for me. Are you on shared hosting? Can be something in the php.ini that's blocking it.

Does the file I am trying to recover the size of have to be on the same server?  Once again, that's what I think the issue might be.

I don't think so, because the way I use that function is to grab the size of external files on many different websites, and it returns the correct value.

filesize() does not work for HTTP/HTTPS. It does work for FTP.

 

get_headers() is php5 only. What php version are you using?
