How to achieve this kind of array merge

Answer 1

Assume both array have the same number of elements and in the same order, then one foreach loop can do the job
$arr1 = Array (
0 => Array (
"id" => "123-456-000-000",
"name" => "john"
),
1 => Array (
"id" => "123-456-789-014",
"name" => "james"
)
);
$arr2 = Array (
0 => Array (
"tin" => "123-456-000-000",
"address" => "Japan"
),
1 => Array (
"tin" => "123-456-789-014",
"address" => "Spain"
)
);
foreach ($arr2 as $key => $inner) {
$arr1[$key]["address"] = $inner["address"];
}
output: $arr1
Array
(
[0] => Array
(
[id] => 123-456-000-000
[name] => john
[address] => Japan
)
[1] => Array
(
[id] => 123-456-789-014
[name] => james
[address] => Spain
)
)

Answer 2

Supposing that your arrays are at the same size and that your IDs are ordered int he same way.
Then you can try:
$arrayReturn = array();
foreach( $array1 as $key1 => $result1 ){
$mergeArray = [$result1['id'], $result1['name'], $array2[$key1]['name']];
array_push($arrayReturn, $mergeArray);
}
Where $array1 and $array2 are both of my initial arrays. $arrayReturn is my result.
Is there no other ways for you to directly merge the arrays at their creation? It would be much more elegant and will avoid all that.
