I want to format a filesize in php as either of these bytes, kilobytes, megabytes, gigabytes according to the size of the file.<\/p>\n

I found the following codes in php.net comments section<\/p>\n

I just copied the following code as it was in the source and i have use only one and not the others.<\/p>\n

You can better directly do this url<\/a> to see the updated function or try the following functions.<\/strong><\/p><\/blockquote>\n

You can find these below the documentation of filesize function. (The comments section of the document).<\/p>\n

\r\nfunction FileSize($file, $setup = null)\r\n{\r\n    $FZ = ($file && @is_file($file)) ? filesize($file) : NULL;\r\n    $FS = array(\"B\",\"kB\",\"MB\",\"GB\",\"TB\",\"PB\",\"EB\",\"ZB\",\"YB\");\r\n    \r\n    if(!$setup && $setup !== 0)\r\n    {\r\n        return number_format($FZ\/pow(1024, $I=floor(log($FZ, 1024))), ($i >= 1) ? 2 : 0) . ' ' . $FS[$I];\r\n    } elseif ($setup == 'INT') return number_format($FZ);\r\n    else return number_format($FZ\/pow(1024, $setup), ($setup >= 1) ? 2 : 0 ). ' ' . $FS[$setup];\r\n}\r\n\r\n<\/pre>\n
Here is another one<\/p>\n
\r\n\r\nfunction format_bytes($size) {\r\n    $units = array(' B', ' KB', ' MB', ' GB', ' TB');\r\n    for ($i = 0; $size >= 1024 && $i < 4; $i++) $size \/= 1024;\r\n    return round($size, 2).$units[$i];\r\n}\r\n\r\n<\/pre>\n
and yet the simplest one as mentioned in the docs<\/p>\n
\r\n\r\nfunction format_bytes($bytes) {\r\n   if ($bytes < 1024) return $bytes.' B';\r\n   elseif ($bytes < 1048576) return round($bytes \/ 1024, 2).' KB';\r\n   elseif ($bytes < 1073741824) return round($bytes \/ 1048576, 2).' MB';\r\n   elseif ($bytes < 1099511627776) return round($bytes \/ 1073741824, 2).' GB';\r\n   else return round($bytes \/ 1099511627776, 2).' TB';\r\n}\r\n\r\n<\/pre>\n
besides, the document said <\/p>\n
It's very interesting but I can't stand the decimals for bytes and KB so here's another example :<\/strong><\/p>\n
\r\n\r\nfunction format_size($size) {\r\n      $sizes = array(\" Bytes\", \" KB\", \" MB\", \" GB\", \" TB\", \" PB\", \" EB\", \" ZB\", \" YB\");\r\n      if ($size == 0) { return('n\/a'); } else {\r\n      return (round($size\/pow(1024, ($i = floor(log($size, 1024)))), $i > 1 ? 2 : 0) . $sizes[$i]); }\r\n}\r\n\r\n<\/pre>\n
and then another contributor said<\/p>\n
This is a short and very clever function to get filesizes.<\/strong><\/p>\n
\r\n\r\nfunction format_size($size) {\r\n      $sizes = array(\" Bytes\", \" KB\", \" MB\", \" GB\", \" TB\", \" PB\", \" EB\", \" ZB\", \" YB\");\r\n      if ($size == 0) { return('n\/a'); } else {\r\n      return (round($size\/pow(1024, ($i = floor(log($size, 1024)))), 2) . $sizes[$i]); }\r\n}\r\n\r\n<\/pre>\n
and it goes on like the above in http:\/\/php.net<\/p>\n

Scroll the page down to see as many as function like the above and suite yourself.<\/p>\n
