disk_total_space

Функция возвращает общий размер в байтах указанного раздела диска или каталога.

Список параметров

Директория файловой системы или раздел диска.

Возвращаемые значения

Возвращает общий размер в байтах в виде числа с плавающей точкой или false в случае возникновения ошибки.

Примеры

Пример #1 Пример использования disk_total_space()

// $df содержит общий размер диска «/» в байтах
$ds = disk_total_space ( «/» );

// В Windows:
$ds = disk_total_space ( «C:» );
$ds = disk_total_space ( «D:» );
?>

Примечания

Замечание: Эта функция неприменима для работы с удалёнными файлами, поскольку файл должен быть доступен через файловую систему сервера.

// Wrong
$exp = floor ( log ( $bytes ) / log ( 1024 ));

//Correct
$exp = $bytes ? floor ( log ( $bytes ) / log ( 1024 )) : 0 ;

For a non-looping way to add symbols to a number of bytes:
function getSymbolByQuantity ( $bytes ) $symbols = array( ‘B’ , ‘KiB’ , ‘MiB’ , ‘GiB’ , ‘TiB’ , ‘PiB’ , ‘EiB’ , ‘ZiB’ , ‘YiB’ );
$exp = floor ( log ( $bytes )/ log ( 1024 ));

return sprintf ( ‘%.2f ‘ . $symbol [ $exp ], ( $bytes / pow ( 1024 , floor ( $exp ))));

To find the total size of a file/directory you have to differ two situations:
(on Linux/Unix based systems only!?)

you are interested:
1) in the total size of the files in the dir/subdirs
2) what place on the disk your dir/subdirs/files uses

— 1) and 2) normaly differs, depending on the size of the inodes
— mostly 2) is greater than 1) (in the order of any kB)
— filesize($file) gives 1)
— «du -ab $file» gives 2)

so you have to choose your situation!

on my server I have no rights to use «exec du» in the case of 2), so I use:
$s = stat($file);
$size = $s[11]*$s[12]/8);
whitch is counting the inodes [12] times the size of them in Bits [11]

hopes this helps to count the used disk place in a right way. 🙂

function roundsize($size) <
$i=0;
$iec = array(«B», «Kb», «Mb», «Gb», «Tb»);
while (($size/1024)>1) <
$size=$size/1024;
$i++;>
return(round($size,1).» «.$iec[$i]);>

Something that might go well with this function is the ability to list available disks. On Windows, here’s the relevant code:

/**
* Finds a list of disk drives on the server.
* @return array The array velues are the existing disks.
*/
function get_disks () <
if( php_uname ( ‘s’ )== ‘Windows NT’ ) <
// windows
$disks =` fsutil fsinfo drives `;
$disks = str_word_count ( $disks , 1 );
if( $disks [ 0 ]!= ‘Drives’ )return » ;
unset( $disks [ 0 ]);
foreach( $disks as $key => $disk ) $disks [ $key ]= $disk . ‘:\\’ ;
return $disks ;
>else <
// unix
$data =` mount `;
$data = explode ( ‘ ‘ , $data );
$disks =array();
foreach( $data as $token )if( substr ( $token , 0 , 5 )== ‘/dev/’ ) $disks []= $token ;
return $disks ;
>
>
?>

EXAMPLE OF USE:

EXAMPLE RESULT:
Array
(
[1] => A:\
[2] => C:\
[3] => D:\
[4] => E:\
[5] => F:\
[6] => G:\
[7] => H:\
[8] => I:\
[9] => M:\
[10] => X:\
[11] => Z:\
)

Warning: This also finds empty disk drives (eg; CD or SMD drives or the more common floppy drive).

Warning2: If you want to find space usage using the info from my function, prepend the disk function with the «@», eg:

//This is a more readable way of viewing the returned float

// $Bytes contains the total number of bytes on «/»
$Bytes = disk_total_space ( «/» );

function dataSize ( $Bytes )
$Type =array( «» , «kilo» , «mega» , «giga» , «tera» );
$counter = 0 ;
while( $Bytes >= 1024 )
$Bytes /= 1024 ;
$counter ++;
>
return( «» . $Bytes . » » . $Type [ $counter ]. «bytes» );
>
?>

Very simple function that convert bytes to kilobytes, megabytes .

return sprintf(«%0.2f Gb», $number/1024/1024/1024);

PHP 6 has already come to the market but still there are no standard function that can help retrieve directory size as it has to calculate disk space such as disk_total_space. Although we can use system level call such as exec() and system(), it is too risky to enable these function. So we look for an alternate method so as to calculate directory size.

Sol: retrieving directory size using php

function get_dir_size ( $dir_name ) $dir_size = 0 ;
if ( is_dir ( $dir_name )) if ( $dh = opendir ( $dir_name )) while (( $file = readdir ( $dh )) !== false ) if( $file != ” . ” && $file != “ .. ” ) if( is_file ( $dir_name . ” / ” . $file )) $dir_size += filesize ( $dir_name . ” / ” . $file );
>
/* check for any new directory inside this directory */
if( is_dir ( $dir_name . ” / ” . $file )) $dir_size += get_dir_size ( $dir_name . ” / ” . $file );
>
>
>
>
>
closedir ( $dh );
return $dir_size ;
>

$dir_name = “directory name here” ;
/* 1048576 bytes == 1MB */
$total_size = round (( get_dir_size ( $dir_name ) / 1048576 ), 2 ) ;
print “Directory $dir_name size : $total_size MB” ;
?>

Depending upon the size format you want to achieve, divide directory size by 1024 or 1024 * 1024 or 1024 * 1024 * 1024 for KB or MB or GB respectively.
