Here is a sample    lt  php    Snippet from PHP Share  http   www phpshare org      function formatSizeUnits  bytes                if   bytes  gt   1073741824                         bytes   number format  bytes   1073741824  2      GB                     elseif   bytes  gt   1048576                         bytes   number format  bytes   1048576  2      MB                     elseif   bytes  gt   1024                         bytes   number format  bytes   1024  2      KB                     elseif   bytes  gt  1                         bytes    bytes     bytes                     elseif   bytes    1                         bytes    bytes     byte                     else                        bytes    0 bytes                      return  bytes      gt

All the answers to the question uses that 1 kilobyte   1024 bytes which is wrong   1 kibibyte   1024 bytes   since the question asks to convert file sizes  it should use that 1 kilobyte   1000 bytes  see https   wiki ubuntu com UnitsPolicy   function format bytes  bytes   precision   2         units   array  B    KB    MB    GB          bytes   max  bytes  0        pow   floor   bytes   log  bytes    0    log 1000         pow   min  pow  count  units  - 1         bytes    pow 1000   pow        return round  bytes   precision           units  pow

This would be a cleaner implementation   function size2Byte  size         units   array  KB    MB    GB    TB         currUnit           while  count  units   gt  0   amp  amp    size  gt  1024             currUnit   array shift  units            size    1024            return   size   0     currUnit

A cleaner approach   function Size  path         bytes   sprintf   u   filesize  path         if   bytes  gt  0                 unit   intval log  bytes  1024             units   array  B    KB    MB    GB             if  array key exists  unit   units      true                        return sprintf   d  s    bytes   pow 1024   unit    units  unit                         return  bytes

This is based on  adnan s great answer   Changes    added internal filesize   call  return early style saving one concatentation on 1 byte   And you can still pull the filesize   call out of the function  in order to get a pure bytes formatting function  But this works on a file            Formats filesize in human readable way         param file  file     return string Formatted Filesize  e g   113 24 MB       function filesize formatted  file         bytes   filesize  file        if   bytes  gt   1073741824            return number format  bytes   1073741824  2      GB         elseif   bytes  gt   1048576            return number format  bytes   1048576  2      MB         elseif   bytes  gt   1024            return number format  bytes   1024  2      KB         elseif   bytes  gt  1            return  bytes     bytes         elseif   bytes    1            return  1 byte         else           return  0 bytes

Even nicer is this version I created from a plugin I found   function filesize formatted  path         size   filesize  path        units   array   B    KB    MB    GB    TB    PB    EB    ZB    YB         power    size  gt  0   floor log  size  1024     0      return number format  size   pow 1024   power   2                     units  power       Note from filesize   doc     Because PHP s integer type is signed and many platforms use 32bit   integers  some filesystem functions may return unexpected results for   files which are larger than 2GB

I think this is a better approach  Simple and straight forward   public function sizeFilter   bytes          label   array   B    KB    MB    GB    TB    PB         for   i   0   bytes  gt   1024  amp  amp   i  lt    count   label   -1     bytes    1024   i          return  round   bytes  2            label  i
