Accessing windows performance counters using PHP - php

Question

I was wondering if it is possible to access windows performance counters using php?
Basically, I already have a PHP application, and I have a basic vb script that accesses the performance counters and creates variables from them. What I need is to be able to access these same performance counters using PHP and therefore set them as variables within my PHP application.
If that isn't possible, is there a way I can use the vb script within the PHP application to use the variables? I would rather not do it this way as I have limited knowledge in that sense, but if that is the only way I will have to learn.
I can post the code if and when required, however for now I just need to know if what I'm asking is possible.
Thanks
EDIT:
My vb code is as follows:
Imports Microsoft.VisualBasic
Imports Microsoft.VisualBasic.CompilerServices
Imports Microsoft.Win32
Imports System
Imports System.Diagnostics
Imports System.Runtime.InteropServices
Imports System.Data.SqlClient
Public Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim perfActiveUsers As New PerformanceCounter("ASP.NET Apps v2.0.50727", "Sessions Active", "__Total__")
Dim perfAlcInstances As New PerformanceCounter("Alchemy Web Pool Manager", "Alchemy Instances Active")
Dim perfAlcAvgResponse As New PerformanceCounter("Alchemy Web Pool Manager", "Request Average Response Time")
Dim perfAlcQueue As New PerformanceCounter("Alchemy Web Pool Manager", "Requests Queued")
Dim perfAlcTimeout As New PerformanceCounter("Alchemy Web Pool Manager", "Requests Timed Out")
Dim perfAlcTotal As New PerformanceCounter("Alchemy Web Pool Manager", "Requests Total")
Dim totalDBs As String = "0"
Dim SQLStr As String
Dim ConnString As String = "Server=ALCHEMYSVR\SQLEXPRESS;Database=AuServer;Integrated Security=SSPI;User Id=STORETECSERVICE\administrator;Password=westend"
Dim SQLConn As New SqlConnection() 'The SQL Connection
Dim SQLCmd As New SqlCommand() 'The SQL Command
Dim SQLdr As SqlDataReader 'The Local Data Store
SQLStr = "SELECT COUNT (*) FROM AusDatabase"
SQLConn.ConnectionString = ConnString 'Set the Connection String
SQLConn.Open() 'Open the connection
SQLCmd.Connection = SQLConn 'Sets the Connection to use with the SQL Command
SQLCmd.CommandText = SQLStr 'Sets the SQL String
SQLdr = SQLCmd.ExecuteReader 'Gets Data
Do
While (SQLdr.Read()) 'While Data is Present
totalDBs = SQLdr(0)
MsgBox(SQLdr(0)) 'Show data in a Message Box
End While
Loop While SQLdr.NextResult() 'Move to the Next Record
SQLdr.Close() 'Close the SQLDataReader
SQLConn.Close() 'Close the connection
'Display The Values
lblAlcInstances.Text = perfAlcInstances.NextValue()
lblActiveUsers.Text = perfActiveUsers.NextValue()
Label1.Text = perfAlcAvgResponse.NextValue()
Label2.Text = perfAlcQueue.NextValue()
Label3.Text = perfAlcTimeout.NextValue()
Label4.Text = perfAlcTotal.NextValue()
Label5.Text = totalDBs
End Sub
End Class
It is the performance counter values that are assigned to the labels at the bottom that I require passing to php as a variable. I have tried the PHP exec but cant grasp how I pass the variables in the vb script to variables in PHP.

It can get a little nasty if you try to fetch windows system data via PHP.
If you already have a VB script, you have two common options:
use exec and parse the data from your script. i would NOT recommend that.
add a little more code to your VB script: it should run periodically and write the current data into a database/key-value-storage/textfile from where you can retrieve the data via php
