Showing Drive Information Using PHP


This article shows how to see all the drive information. In this article we use a COM object. COM is an abbreviate of Component Object Model; this object is an object oriented layer on top of DCE RPC (open standard) and defines a common calling rules that is followed by any language. The code can be loaded from a DLL.
There is a subset of COM known as OLE Automation that is a set of COM interfaces that allow loose binding to COM Objects, so that we called them run-time without compile-time knowledge of how the object works. The PHP COM extension utilizes the OLE Automation interface to allow us to create and call something.
COM is the only way to communicate with a Windows platform. Using COM we can launch a Microsoft Word document, like open a Word document, do any task in Word and send it to a visitor's web site.


$obj= new COM("Application.ID")

If you will encounter any Fatel error : Class \'COM'\ not found
Add this code into your php.ini file


$obj= new COM("Application.ID")

If you encounter a Fatel error : Class \'COM'\ not found


Then use the following procedure to remove this fatal error.

Step 1

Open the php.ini file. It might be in the file location "C:\Program Files\IIS Express\PHP\v5.4".

Step 2


And paste the following code as shown in the picture .


$fileObj = new COM('Scripting.FileSystemObject');
$DriveObj = $fileObj->Drives;
$type = array("Unknown","Removable","Fixed","Network","CD-ROM","RAM Disk");
foreach($DriveObj as $d )
     $dO = $fileObj->GetDrive($d);
     $s = "";
     if($dO->DriveType == 3)
         $n = $dO->Sharename;

     $n = $dO->VolumeName;
     $s = sizeOfFile($dO->FreeSpace) . " free of: " . sizeOfFile($dO->TotalSize);
     $n = "[Drive not ready]";
     echo "Drive " . $dO->DriveLetter . ": - " . $type[$dO->DriveType] . " - " . $n . " - " . $s . "<br>";
function sizeOfFile($size)
    $filesizename = array(" Bytes", " KB", " MB", " GB");
    return $size ? round($size/pow(1024, ($i = floor(log($size, 1024)))), 2) . $filesizename[$i] : '0 Bytes';
