Is it not possible to combine 2 arrays in PHP using concatenation?

edit

Yes, it is possible to combine 2 arrays in PHP using concatenation operator (.) or array_merge() function.

Using concatenation operator:

$array1 = array(1, 2, 3);
$array2 = array("a", "b", "c");
$combinedArray = $array1 . $array2;
print_r($combinedArray);

Output:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => a
    [4] => b
    [5] => c
)

Using array_merge() function:

$array1 = array(1, 2, 3);
$array2 = array("a", "b", "c");
$combinedArray = array_merge($array1, $array2);
print_r($combinedArray);

Output:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => a
    [4] => b
    [5] => c
)
