note 68790 added to function.glob

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? ---- Server IP: 64.71.164.2 Probable Submitter: 67.3.199.113 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.glob.php Edit -- https://master.php.net/note/edit/68790 Del: integrated -- https://master.php.net/note/delete/68790/integrated Del: useless -- https://master.php.net/note/delete/68790/useless Del: bad code -- https://master.php.net/note/delete/68790/bad+code Del: spam -- https://master.php.net/note/delete/68790/spam Del: non-english -- https://master.php.net/note/delete/68790/non-english Del: in docs -- https://master.php.net/note/delete/68790/in+docs Del: other reasons-- https://master.php.net/note/delete/68790 Reject -- https://master.php.net/note/reject/68790 Search -- https://master.php.net/manage/user-notes.php
