问题
I am running my PHP code on my local computer,So ,I just want to know the PHP has any functions to get the local hard disk information.Such as the disk name , disk space,free space available .etc.
Thank you very much!!

In addition, yes, it is possible to retrieve this information, because you can execute commands. There are a few PHP functions to retrieve information about the disk as well, check out the following links:
- disk_total_space( $directory );
- disk_free_space( $directory );
Retrieving the disk's name, however, needs to be done with a command. I've just booted Windows in VirtualBox and it seems the following would work:
if( preg_match( '~Volumenaam : (.*)~i', `fsutil fsinfo volumeinfo C:\\`, $matches ) ) {
echo $matches[1];
}
Volumenaam is Dutch for "Volumename". I only have the Dutch version of Windows, so you'd have to check what the actual string is.
Good luck.

Builtins:
- disk_free_space()
- disk_total_space()
If you need more, you can access local commands via system().
For disk usage, you'll also find different snippets on the net, e.g. this:
- http://justynshull.com/2010/08/du2-php/, which uses shell_exec().

There are two functions: disk_free_space() and disk_total_space().

Did you try searching the PHP manual before you asked here?
These two functions came up very quickly for me:
- disk_total_space()
- disk_free_space()
Further data such as the disc name may be trickier (you may need to use system() as per another answer here), but that should give you a start.
However, note that when PHP is running in a web site, it will have quite a lot of restrictions on what it can do; it's likely to be restricted to its local web folders for any disc access.
