PHP get all disk space size of server _php tutorial

There are times when you need to get disk space usage in normal programming, and most of the time you use the Disk_free_space and Disk_total_space functions.

The following example is to obtain the server all disk space size, the example is as follows:

/**

* Byte formatting converts the size of the byte number format to the B K M G T P E Z Y Description

* @param int $size size

* @param int $DEC Display Type

* @return int

*/

function Byte_format ($size, $dec =2)

{

$a = Array ("B", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB");

$pos = 0;

while ($size >= 1024)

{

$size/= 1024;

$pos + +;

}

Return round ($size, $dec). " ". $a [$pos];

}

/**

* Obtain individual disk information

* @param $letter

* @return Array

*/

function Get_disk_space ($letter)

{

Get disk information

$DISKCT = 0;

$disk = Array ();

/*if (@disk_total_space ($key)!=null) * To prevent the server from being affected, do not check the floppy drive

{

$DISKCT = 1;

$disk ["A"]=round ((@disk_free_space ($key)/(1024*1024*1024)), 2). " G/". Round ((@disk_total_space ($key)/(1024*1024*1024), 2). ' G ';

}*/

$diskz = 0; Total disk capacity

$DISKK = 0; Disk remaining capacity

$is _disk = $letter. ': ';

if (@disk_total_space ($is _disk)!=null)

{

$diskct + +;

$disk [$letter][0] = Byte_format (@disk_free_space ($is _disk));

$disk [$letter][1] = Byte_format (@disk_total_space ($is _disk));

$disk [$letter][2] = Round (((@disk_free_space ($is _disk)/(1024*1024*1024)/(@disk_total_space ($is _disk)/(1024*1024 *1024)) *100,2). ' %';

$DISKK +=byte_format (@disk_free_space ($is _disk));

$diskz +=byte_format (@disk_total_space ($is _disk));

}

return $disk; Www.2cto.com

}

/**

* Get disk usage

* @return var

*/

function Get_spec_disk ($type = ' system ')

{

$disk = Array ();

Switch ($type)

{

Case ' system ':

Strrev (Array_pop (Explode (': '), Strrev (Getenv_info (' SystemRoot '))));//Get system drive letter

$disk = Get_disk_space (Strrev (Array_pop (Explode (': '), Strrev (getenv (' SystemRoot '))));

Break

Case ' all ':

foreach (Range (' B ', ' Z ') as $letter)

{

$disk = Array_merge ($disk, Get_disk_space ($letter));

}

Break

Default

$disk = Get_disk_space ($type);

Break

}

return $disk;

}

This allows you to expand your disk, such as getting the overall disk space size, the remaining space on the disks.

Here also have to re-explain, if the server has a floppy disk remember to avoid, otherwise the server-related floppy disk running program has a fixed obstacle, using the program to read all disk usage may be slow! Attention!
