            [name] => james
        )

    [2] => Array
        (
            [tin] => 123-456-000-000
            [address] => Japan
        )

    [3] => Array

What i wanted is

Array

        (
            [id] => 123-456-000-000
            [name] => john
            [address] => Japan
        )

    [1] => Array

            [name] => james
            [address] => Spain
        )

)

How to achieve this kind of array merge

@Terminus what do you mean by equal length?if you mean same number of array yes always.but there are more values i just shorten them. in first array there are last name etc. while second one it breaks down to country city district..i hope i answered it correctly — guradio, Dec 09 '15 at 04:17
@Terminus because they are pair...in one array it is personal information of the person and the other is the address information — guradio, Dec 09 '15 at 04:19
Just compare one by one. Take a look here http://stackoverflow.com/questions/13669554/merging-two-multidimensional-arrays-on-specific-key It might solve your problem but I am sure it isn't the best way. — Thuong Nguyen, Dec 09 '15 at 04:32

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
        )

)

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.
