[dr_aybyd]

Is there any good way to convert a vb.net code into PHP?
Here is my code function that want to convert into php. Tia

Dim valuearray As Byte() = New Byte(3) {}
        Dim s As String = myMD5res
        Dim rx As New Regex("\w{2}")
        Dim mc As MatchCollection = rx.Matches(s)
        Dim sb As New StringBuilder()
 
        Dim n As Integer = mc.Count / 4
        For i As Integer = 0 To n - 1
            For j As Integer = 0 To n - 1
                valuearray(j) = Convert.ToByte(mc(i + (j * n)).Value, 16)
            Next
            Dim value As Integer = valuearray(0) Xor valuearray(1) Xor valuearray(2) Xor valuearray(3)
 
            sb.Append(value.ToString("X2"))
        Next
 
        Dim hex32 As String = sb.ToString()
        Dim myCodes As Integer = ("&H" & hex32 And &H1FFFFFF) Or &H2000000
        Dim newCodes As String = myCodes.ToString("X2")
 
        Dim hexNumber As [String] = newCodes
        Dim hextodecs As Integer = Int32.Parse(hexNumber, NumberStyles.HexNumber)
        TextBox1.Text = hextodecs
