Array merging issue

Question

I've following two arrays as follows,

$array1 = array
    (
        'Name' => 'Scott',
        'Department' =>  'Sales',
        'Location' => 'USA',
        'Details' => array
            (
                15 => '90%', 
                16 => '75%',
                17 => '50%',
                18 => '60%',
                19 => '50%',
                20 => '45%',  
            ),
          );
$array2 = array
(
    'Action' => 'Imp',
    'Name' => 'Scott',
    'Department' => 'Sales',
    'Location' => 'Canada', 
    'Details' => array 
    (
             15 => '20%', 
             16 => '15%',
             17 => '25%',
             18 => '10%',
    ),
);

Result should be:

$result_arr = array
        (
            'Action' => 'Imp',
            'Name' => 'Scott',
            'Department' =>  'Sales',
            'Location' => 'Canada',
            'Details' => array
                (
                    15 => '20%', 
                    16 => '15%',
                    17 => '25%',
                    18 => '10%',
                    19 => '50%',
                    20 => '45%',  
                ),
              );

I've tried array_merge and array union (+) operator but none of them is fit for my requirement.

Can you provide more detail about the merge requirement? What causes the value of 'sales' to be retained over 'Sales'? 'Canada' over 'USA'? — George Cummins

You answerd the sales/Sales part, but not the USA/Canada part. — George Cummins

is the custom_field in the $array2 a typo as well or its a business logic that requires it to be merged into Details key? — Fikri Marhan

What are you getting when you merge them? Can you show us the code you use to merge? — Pitchinnate

Try this

$final= array_merge($array1,$array2);
$final['Details']= $final['Details']+$array1['Details'];
asort($final);
echo "<pre>"; print_r($final);

Output :

Array
(
    [Location] => Canada
    [Action] => Imp
    [Department] => Sales
    [Name] => Scott
    [Details] => Array
        (
            [15] => 20%
            [16] => 15%
            [17] => 25%
            [18] => 10%
            [19] => 50%
            [20] => 45%
        )

)

It seems that resulting array should look like $array2 and $array2['Details'] should be extended with keys from $array1['Details']

$result_arr = $array2;
$result_arr['Details'] += $array1['Details'];

With as little info that was provided, I was able to get your result using this:

$array = array_merge($array1, $array2);
$array['Details'] = $array2['Details'] + $array1['Details'];
print_r($array);

The Result:

Array
(
    [Name] => Scott
    [Department] => Sales
    [Location] => Canada
    [Details] => Array
        (
            [15] => 20%
            [16] => 15%
            [17] => 25%
            [18] => 10%
            [19] => 50%
            [20] => 45%
        )

    [Action] => Imp
)

$array2['Details'] = array_merge($array1['Details'], $array2['Details']);
$result = $array2;
