Getting Disk Type

[nblackwood]

Is there any possible way to determine a drive type (e.g., hard disk, dvd drive, usb drive, etc.) and partition type (e.g., NTFS, CDFS, ext3, etc.) in php without the use of COM and importing OS resources? I ask, because I am developing a custom system explorer for a web application. I already know how to detect drives, drive size/usage and associated drive letters, but am curious if any built-in functions of php can do this. Any help is appreciated.
