PHP gets the size of all disk space on the server_PHP tutorial

In daily programming, it is sometimes necessary to obtain disk space usage. In most cases, the disk_free_space and disk_total_space functions are used.
The following example is to obtain the size of all disk space of the server. The example is as follows:
/**
* Byte formatting Format the number of bytes into the size described by B K M G T P E Z Y
* @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];
}
/**
* Get single 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 affecting the server, the floppy drive is not checked
{
$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 the 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;
}
From this, you can expand it, such as getting the overall disk space size and the remaining disk space.
I have to reiterate here, if the server has a floppy disk, remember to avoid it, otherwise it will hinder the server-related floppy disk running program, and using the program to read all disk usage may be slow! Notice!
