How to append this array as it is in php - php

Question

I need to append this array in php script
.Kindly help to do it perfectly .I tried multiple solution but none resulted to correct solution.
Array(
[Donn] => 0
[Lamo] => 0
[Otis] => 0
[Stev] => 0
[Matt] => 0
[Samm] => 0
[Andr] => 0
[Jerr] => 0
[Simm] => 0
[Steph] => 0
[Fredd] => 0
[Willi] => 0
)
to the following array
Array(
[Don] => Array
(
[Ab] => 1
[Ang] => 1
[Ant] => 2
[Bo] => 1
[Ch] => 1
[Chri] => 2
[Chri] => 4
[Deau] => 1
[Der] => 1
[Sylveste] => 1
)
[Lam] => Array
(
[Ab] => 2
[Ch] => 22
[Dona] => 1
[Irw] => 1
[Kou] => 1
[Llo] => 1
[Ro] => 1
[Shumy] => 1
)
[Oti] => Array
(
[Ab] => 1
[Arla] => 1
[Kour] => 1
[Osh] => 1
[Roy ] => 1
[Tim] => 1
[War] => 1
//add the given array here
))
So that the result is
Array([Don] => Array
(
[Ab] => 1
[Ang] => 1
[Ant] => 2
[Bo] => 1
[Ch] => 1
[Chri] => 2
[Chri] => 4
[Deau] => 1
[Der] => 1
[Sylveste] => 1
)
[Lam] => Array
(
[Ab] => 2
[Ch] => 22
[Dona] => 1
[Irw] => 1
[Kou] => 1
[Llo] => 1
[Ro] => 1
[Shumy] => 1
)
[Oti] => Array
(
[Ab] => 1
[Arla] => 1
[Kour] => 1
[Osh] => 1
[Roy ] => 1
[Tim] => 1
[War] => 1
[Donn] => 0
[Lamo] => 0
[Otis] => 0
[Stev] => 0
[Matt] => 0
[Samm] => 0
[Andr] => 0
[Jerr] => 0
[Simm] => 0
[Steph] => 0
[Fredd] => 0
[Willi] => 0
//added here
))
Please use least loops as much as possible.So as to get time feasible solution.Use php array function if possible.

Answer 1

Use foreach to add into the oti index:
<?php
$firstArr = Array(
"Don" => Array
(
"Ab" => 1,
"Ang" => 1,
"Ant" => 2,
"Bo" => 1,
"Ch" => 1,
"Chri" => 2,
"Chri" => 4,
"Deau" => 1,
"Der" => 1,
"Sylveste" => 1,
),
"Lam" => Array
(
"Ab" => 2,
"Ch" => 22,
"Dona" => 1,
"Irw" => 1,
"Kou" => 1,
"Llo" => 1,
"Ro" => 1,
"Shumy" => 1,
),
"Oti" => Array
(
"Ab" => 1,
"Arla" => 1,
"Kour" => 1,
"Osh" => 1,
"Roy " => 1,
"Tim" => 1,
"War" => 1,
//add the given array here
));
$secondArr = Array(
"Donn" => 0,
"Lamo" => 0,
"Otis" => 0,
"Stev" => 0,
"Matt" => 0,
"Samm" => 0,
"Andr" => 0,
"Jerr" => 0,
"Simm" => 0,
"Steph" => 0,
"Fredd" => 0,
"Willi" => 0,
);
foreach ($secondArr as $key => $value) {
$firstArr["Oti"][$key] = $value;
}
print_r($firstArr);
Demo
You can also use array_merge as #Mark Baker said in comments:
$firstArr["Oti"] = array_merge($firstArr["Oti"], $secondArr);

Answer 2

This should solve it, you use the array_merge function to merge the 2 arrays :)
$secondArray['Oti'] = array_merge($secondArray['Oti'], $firstArray);
