bug: error while generating $arr[] = Elem;

[i582]

<?php

function F() {
    $arr = 5;
    $arr = ["5"];

    $arr[] = "22";
    echo $arr;
}

Actual Code

func F() {
	arr := NewVar()
	arr.Setint64(5)
	arr.SetElementTypestring([]string{"5"})
	arr.GetElementTypestring() = append(arr.GetElementTypestring(), "22")
	fmt.Print(arr.GetElementTypestring())
}

Expected Code

func F() {
	arr := NewVar()
	arr.Setint64(5)
	arr.SetElementTypestring([]string{"5"})
	arr.SetElementTypestring(append(arr.GetElementTypestring(), "22"))
	fmt.Print(arr.GetElementTypestring())
}
