note 111106 added to function.filesize

Rommel posted a nice human_filesize() implementation, and I wanted to post a few refinements I made. The biggest change is I limited the factor to the range of the $sz variable, rather than used error suppression. I also used the IEC/NIST suggested abbreviations. <?php function human_filesize($filesize, $decimal_places=2) { $sz = 'BKMGTPEZY'; $factor = min(max(0, floor(strlen($size) / 3)), 8); return sprintf("%.{$decimal_places}f ", $size / pow(1024, $factor)) . $sz[$factor] . ($factor > 0 ? 'iB' : ''); } ?> ---- Server IP: 69.147.83.199 Probable Submitter: 69.255.131.117 ---- Manual Page -- http://php.net/manual/en/function.filesize.php Edit -- https://master.php.net/note/edit/111106 Del: integrated -- https://master.php.net/note/delete/111106/integrated Del: useless -- https://master.php.net/note/delete/111106/useless Del: bad code -- https://master.php.net/note/delete/111106/bad+code Del: spam -- https://master.php.net/note/delete/111106/spam Del: non-english -- https://master.php.net/note/delete/111106/non-english Del: in docs -- https://master.php.net/note/delete/111106/in+docs Del: other reasons-- https://master.php.net/note/delete/111106 Reject -- https://master.php.net/note/reject/111106 Search -- https://master.php.net/manage/user-notes.php
