Php obtains the size of all disk space on the server.

 

In common programming, you sometimes need to obtain disk space usage. In most cases, the disk_free_space and disk_total_space functions are used.

 

The following instance obtains the disk space of all servers. The instance is as follows:

 

/**

* In byte format, the number of bytes is in the format of B K M G T P E Z Y.

* @ Param int $ 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 information about a single disk

* @ Param $ letter

* @ Return array

*/

Function get_disk_space ($ letter)

{

// Obtain disk Information

$ Diskct = 0;

$ Disk = array ();

/* If (@ disk_total_space ($ key )! = NULL) * to prevent server impact, do not check the disk 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; // remaining disk 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 ). '% ';

$ Diskk + = byte_format (@ disk_free_space ($ is_disk ));

$ Diskz + = byte_format (@ disk_total_space ($ is_disk ));

}

Return $ disk; www.2cto.com

}

 

/**

* Obtain disk usage

* @ Return var

*/

Function get_spec_disk ($ type = 'system ')

{

$ Disk = array ();

Switch ($ type)

{

Case 'system ':

// Strrev (array_pop (explode (':', strrev (getenv_info ('systemroot'); // obtain 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;

}

 

 

 

You can expand the disk space, such as obtaining the overall disk space and remaining disk space.

Here, we have to re-explain that if the server has a floppy disk, remember to avoid it. Otherwise, it will hinder the program running on the disk, the usage of the program to read all disks may be slow! Note!
