How to reverse an array in php WITHOUT using the array reverse method

Question

I have an array called reverse array and I want to reverse it.

This is my code:

<?php

//Task 21 reverse array

$reverseArray = array(1, 2, 3, 4);
$tmpArray = array();
$arraySize = sizeof($reverseArray);

for($i<arraySize; $i=0; $i--){
    echo $reverseArray($i);
}

?>

I want to know how to reverse an array without using the array_reverse method. Can someone please point out the mistake in my code?
