TalkPHP - Correcting negative filesize() bug for larger files

As you may know, PHP 5.2.13 has an issue with determining the size of a large file. The number of bytes will be displayed as a negative if the file size is too large. I've come up with a very simple fix and made a way to display the files in a list with the size as it should be seen (eg if the size is within the range of kb/mb/gb

PHP Code:


		
			
<?php
$handle=opendir(".");
while (($file = readdir($handle))!==false) {
if ( !in_array($file, array(".", "..", "index.php")) && is_file($file) ) {
echo "<a href='$file'>$file</a>";
$b = filesize($file);
if ( $b < 0 ) $b = $b - $b - $b;
$kb = $b / 1024;
$mb = $kb / 1024;
$gb = $mb / 1024;
if ( $mb >= 1024 ) echo " " . round($gb, 2) . " gb";
if ( $kb >= 1024 && $gb < 1) echo " " . round($mb, 2) . " mb";
if ( $b >= 1024 && $mb < 1 ) echo " " . round($kb, 2) . " kb";
if ( $b < 1024 ) echo " " . $b . " b";
echo "<br>";
}
}
closedir($handle);
?>
