PHP - Merge 2 multidimensional array based on value - php

Question

Currently, I have 2 multidimensional array and I'm looking to combine them into one giant array where the value's name in array 1 matches the value's name in array 2.
The array's look as followed...
Array1
(
[0] => Array
(
[id] => 1
[name] => test1
[desc] => test_desc
[quantity] => 3
)
[1] => Array
(
[id] => 2
[name] => test2
[desc] => test_desc
[quantity] => 33
)
)
Array2
(
[0] => Array
(
[holder] => 'John'
[name] => test1
[desc] => test_desc
[location] => ATL
)
[1] => Array
(
[holder] => 'Jackie'
[name] => test3
[desc] => test_desc
[location] => SF
)
)
I'm looking to merge the arrays where the 'name' column in array1 matches in array2 and also combine the columns in array's 1 & 2 into the final array. This should look like...
FinalArray
(
[0] => Array
(
[id] => 1
[holder] => 'John'
[name] => test1
[desc] => test_desc
[location] => ATL
[quantity] => 3
)
[1] => Array
(
[holder] => 'Jackie'
[name] => test3
[desc] => test_desc
[location] => SF
)
[2] => Array
(
[id] => 2
[name] => test2
[desc] => test_desc
[quantity] => 33
)
)
Where the "test1" combines the different columns across the 2 arrays into a new array inside the "FinalArray". I've tried researching some ideas with array_merge and array_merge_recursive but I'm not entirely sure if I'm going in the correct direction. Thanks in advance.

Answer 1

Try like this
$array1=[['id' => 1,'name' => 'test1','desc' => 'test_desc','quantity' => 3],
['id' => 2,'name' => 'test2','desc' => 'test_desc','quantity' => 33]];
$array2=[['holder' => 'John','name' => 'test1','desc' => 'test_desc','location' => 'ATL'],
['holder' => 'Jackie','name' => 'test3','desc' => 'test_desc','location' => 'SF']];
$final=[];
foreach ($array1 as $key1=>$data1){
foreach ($array2 as $key2=>$data2){
if($data1['name']==$data2['name']){
$final[]=$data1+$data2;
unset($array1[$key1]);
unset($array2[$key2]);
}
}
}
if(!empty($array1)){
foreach ($array1 as $value){
$final[]=$value;
}
}
if(!empty($array2)){
foreach ($array2 as $value){
$final[]=$value;
}
}
It will give output as

One more solution
function merge_by_name(array $arr1, array $arr2) {
$result = [];
foreach ($arr1 as $value) {
$key = array_search($value['name'], array_column($arr2, 'name'));
if($key !== false) {
$result[] = array_merge($value, $arr2[$key]);
unset($arr2[$key]);
} else {
$result[] = $value;
}
}
$result = array_merge($result, $arr2);
return $result;
}
Test
$arr1 = [
[
'id' => 1,
'name' => 'test1',
'desc' => 'test_desc',
'quantity' => 3
],
[
'id' => 2,
'name' => 'test2',
'desc' => 'test_desc',
'quantity' => 33
],
];
$arr2 = [
[
'holder' => 'John',
'name' => 'test1',
'desc' => 'test_desc',
'location' => 'ATL'
],
[
'holder' => 'Jackie',
'name' => 'test3',
'desc' => 'test_desc',
'location' => 'SF'
],
];
var_export(merge_by_name($arr1, $arr2));
Result
array (
0 =>
array (
'id' => 1,
'name' => 'test1',
'desc' => 'test_desc',
'quantity' => 3,
'holder' => 'John',
'location' => 'ATL',
),
1 =>
array (
'id' => 2,
'name' => 'test2',
'desc' => 'test_desc',
'quantity' => 33,
),
2 =>
array (
'holder' => 'Jackie',
'name' => 'test3',
'desc' => 'test_desc',
'location' => 'SF',
),
)
