filesize() [function.filesize]: stat failed

Question

I am getting the following error when trying to echo the HTML contents of a file inside a wordpress plugin folder.

Warning: filesize() [function.filesize]: stat failed for http://bestideabox.com/wp-content/plugins/jww-namechord/ includes/template-files/single-form.html in /home/bestidea/public_html/wp-content/plugins/ jww-namechord/includes/core.php on line 44

Here is the function that reads the file:

return jww_display_file( 
        plugins_url( 'template-files/'.$template.'.html',__FILE__ ) 
    );


        function jww_display_file( $fileToRead ){

            //Open the file and read it
            $handle = fopen( $fileToRead, "r" );
            $contents = fread( $handle, filesize( $fileToRead ) );
            fclose( $handle );

            //return it
            return $contents;
        }           

I am at a complete loss. Any Help would be appreciated.

Not sure how to mark this as an answer, but thanks to DaveRandom I have a solution:

The http:// wrapper does not support stat(). You cannot filesize() a HTTP URL. You can use the Content-Length: header of the response if the server returns one, but you actually don't need to here. Just replace the entire body of that function with return file_get_contents($fileToRead); and you're set. – DaveRandom

To those who marked as duplicate. You can see from answer it is not the same issue. Thanks guys for all your help!
