php - How to get the disk space on a server?

Question

I should to develop a web-application in php for a firm, and I need to know the disk free space of the server.

At the moment, I'm able to obtain the free disk space of this kind :

 $quota="104857600"; //100Mb : (100*1024*1024)

after, I do the difference between $quota and my size variable.

So, in this case, I must to write the disk size directly in the php file...

It's possible to do the disk capacity ?
