Since we concluded in the comments that you actually want a multidimensional array, we need to create new arrays so we can swap the values around between the original arrays.

Here's one possible solution (the comments explain the different parts)

$a = [1,2];
$b = [3,4];

// Initiate a new array
$newArray = [];

// Iterate through one of the arrays
foreach ($a as $index => $value) {
    // On each iteration, take the values from both arrays for that specific array index
    // and add them as a new sub array.
    $newArray[] = [
        $a[$index],
        $b[$index]
    ];
}

$newArray will now contain a multidimensional array:

[[1,3],[2,4]]
