Answer 1

You can use array_replace

$arr1 = [
    'x' => '42', 
    'y' => '551',
    'a' => '512',
    'b' => 'gge',
];


$arr2 = [
    'a' => 'ordered',
    'x' => 'this',
    'y' => 'is',
    'b' => 'now',
];

$arr2 = array_replace($arr1, $arr2);

$arr2 is now

[
    'x' => this,
    'y' => is,
    'a' => ordered,
    'b' => now,

]
