filesize() function does not work

I uploaded some files to a folder, and when I use filesize function I get this message:

Message: filesize() [function.filesize]: stat failed for http://www.books.tahasoft.com/216.ppt

the path of file is: 

http://www.books.tahasoft.com/216.ppt

and here is my code:

<?
echo filesize("http://www.books.tahasoft.com/216.ppt");
?>

How can I fix this?

for getting the size of your file from filesize() function, you need to add folder path of the file to get the size.

==> False Method: $filePath = "http://www.books.tahasoft.com/216.ppt";

==> True Method: folder path like: $filePath = '/home/www/uploadpath/filename';

So, you get the result by calling the function like:

filesize($filePath);

OR

If you want to get the size from the link, you have to do like this:

strlen(file_get_contents("http://www.books.tahasoft.com/216.ppt"));

You can use like this....... 

 $ch = curl_init('http://www.books.tahasoft.com/216.ppt');
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
 curl_setopt($ch, CURLOPT_HEADER, TRUE);
 curl_setopt($ch, CURLOPT_NOBODY, TRUE);
 $data = curl_exec($ch);
 $size = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);

 curl_close($ch);
 echo $size;

The best you can do, to perform a HTTP HEAD request to the file, and check existence of the Content-Length header; the only other way would be to download the whole file, and check its length - but in my opinion is not a real option.

You could do this instead.

echo strlen(file_get_contents("http://www.books.tahasoft.com/216.ppt"));

The http:// stream wrapper does not support the stat family of functions, so you can't do this with filesize as the documentation warns:

As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to Supported Protocols and Wrappers to determine which wrappers support stat() family of functionality.

If you need the filesize over HTTP without having to download the whole file first, you might be able to get it using curl; you can see how to do that here. But keep in mind that this is dependent on what headers the remote server decides to send back; there is no guarantee that it will always work.

You cannot get the filesize over the http protocol.

If the file is on the local server, use filesize with a absolute or a relative path in the filesystem.
