I was making a directory filesize function but found there's a slight difference between glob
and readdir in terms of getting sizes.
<?php
function dirsize_glob($dir)
{
$size = 0;
$dir .= (!ereg('/$', $dir)) ? '/' : '';
foreach (glob($dir . '*') as $file)
{
$size += (is_dir($file)) ? dirsize_glob($file) : filesize($file);
}
return $size;
}
function dirsize_readdir($dir)
{
$size = 0;
$dir .= (!ereg('/$', $dir)) ? '/' : '';
$handle = opendir($dir);
while (($file = readdir($handle)) !== FALSE)
{
if (!ereg('^\.{1,2}$', $file))
{
$size += (is_dir($dir . $file)) ? dirsize_readdir($dir . $file) : filesize($dir . $file);
}
}
closedir($handle);
return $size;
}
?>
For a directory that's 529216 bytes, readdir correctly gives 529216 while glob gives 528996, a
difference of 220 bytes. Anyone know why there's such a difference?
