A VBScript equivalent of PHP’s strstr

Function strstr( haystack, needle, before_needle )

    Dim pos
    If varType(before_needle) <> 11 Then before_needle = false

    pos = Instr(1,haystack,needle,vbBinaryCompare)

    If pos <= 0 Then
        strstr = false
    Else
        If before_needle Then
            strstr = Mid(haystack,1,pos-1)
        Else
            strstr = Mid(haystack,pos)
        End If
    End If

End Function
