Append array values to another array by keys comparison

Question

I've this two arrays:

$arr1['someKey'] = [1,2,3,4,5];
$arr2['someKey'] = [6,7];

how do I add|append the values from the second one into the first one by comparing it's keys? The result should be something like:

$arr3['someKey'] = [1,2,3,4,5,6,7];

Any help?

i am not sure what exactly you want but print_r(array_merge($arr1['someKey'],$arr2['someKey'])); will work — Mayank K. Swami

Try array_merge_recursive:

$arr1 = array(
    'someKey' => [1,2,3,4,5],
);
$arr2 = array(
    'someKey' => [6,7],
);

$merged = array_merge_recursive($arr1, $arr2);

please check on your way should work.

$arr3 = $arr1 + $arr2; 

print_r($arr3);

as same as array_merge but preserved array keys.

Try this..

array_merge_recursive() merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array.

$arr3 = array_merge_recursive($arr1, $arr2);
print_r($arr3);
