Need to merge two Arrays like 1st value of first array followed by first value of second array and so on in php

I have 2 arrays
Say Example
A1 = [1,2,3] A2 = [4,5,6]

The output I need is
A3 = [1,4,2,5,3,6]

i.e the output I need is first value of first array followed by first value of second array and so on

How can I achieve this in PHP

I tired some php array functions ,I didn’t get the my required result

    Here is a way to do it (assuming that both arrays have the same size):

    function merge($a1, $a2)
{
    $a3 = [];
    $len = count($a1);
    for($i=0;$i<$len;$i++)
    {
        $a3 []= $a1[$i];
        $a3 []= $a2[$i];
    }
    return $a3;
}

$a1 = [1, 2, 3];
$a2 = [4, 5, 6];
$a3 = merge($a1, $a2);
var_dump($a3);

    Maybe you can do something like this:

    $longer_arr = count($arr1) > count($arr2) ? $arr1 : $arr2;

$shorter_arr = count($arr1) > count($arr2) ? $arr2 : $arr1;

$combined_arr = [];
foreach($longer_arr as $key => $val){
    $combined_arr[] = $val;
    if(isset($shorter_arr[$key])){
        $combined_arr[] = $shorter_arr[$key];
    }
}

    P.s I didn’t tested it
