note 62656 added to function.filesize

here a piece of code to format a filesize: <?php function formatbytes($val, $digits = 3, $mode = "SI", $bB = "B"){ //$mode == "SI"|"IEC", $bB == "b"|"B" $si = array("", "k", "M", "G", "T", "P", "E", "Z", "Y"); $iec = array("", "Ki", "Mi", "Gi", "Ti", "Pi", "Ei", "Zi", "Yi"); switch(strtoupper($mode)) { case "SI" : $factor = 1000; $symbols = $si; break; case "IEC" : $factor = 1024; $symbols = $iec; break; default : $factor = 1000; $symbols = $si; break; } switch($bB) { case "b" : $val *= 8; break; default : $bB = "B"; break; } for($i=0;$i<count($symbols)-1 && $val>=$factor;$i++) $val /= $factor; $p = strpos($val, "."); if($p !== false && $p > $digits) $val = round($val); elseif($p !== false) $val = round($val, $digits-$p); return round($val, $digits) . " " . $symbols[$i] . $bB; } //some test cases: function test($i, $digits = 3, $mode = "SI", $bB = "B"){ echo $i . " = " . formatbytes($i, $digits, $mode, $bB) .
