A VBScript equivalent of PHP’s array_filter

Function array_filter(ByRef mAry,callback)

    If isArray(mAry) Then

        Dim intCounter,i,strType,callback_ret
        intCounter = uBound(mAry)

        For i = 0 to intCounter
            callback_ret = true
            If Len( callback ) > 0 Then _
                execute("callback_ret = " & callback & "(mAry(i))")

            If callback_ret = true and ( mAry(i) = empty or isNull(mAry(i)) ) Then
                mAry = array_remove(mAry,i)
                call array_filter(mAry,callback)
                Exit For
            End If
        Next

    ElseIf isObject(mAry) Then
        Dim j
        For Each j IN mAry
            callback_ret = true
            If Len( callback ) > 0 Then _
                execute("callback_ret = " & callback & "(mAry(i))")

            If callback_ret = true and ( mAry(j) = empty or isNull(mAry(j)) ) Then _
                mAry.Remove j
        Next

    End If

    array_filter = true

End Function
