Re-arranging and combining an array - php

Question

I'm having an issue when I dump the array below. This dumps several arrays. Some are 2 some are 3, which complicates it even more. Basically what I want I put below. I have tried array_push, array_combine, array_merge, several different ways including $array[$param] = $insertValue and I'm stuck. I am open to creating a brand new array too.
Please note not all arrays are counts of 3 but always return at least 1.
Original array:
array(3) {
[0]=>
array(2) {
["contact_id"]=>
string(9) "CONTACTID"
["contact_id_content"]=>
string(19) "123456789123456"
}
[1]=>
array(2) {
["sm_owner"]=>
string(9) "SMOWNERID"
["sm_owner_content"]=>
string(19) "123456798452"
}
[2]=>
array(2) {
["contact_owner"]=>
string(13) "Contact Owner"
["contact_owner_content"]=>
string(16) "Jane Doe"
}
Array desired:
array(3) {
[0]=>
array(6) {
["contact_id"]=>
string(9) "CONTACTID"
["contact_id_content"]=>
string(19) "123456789123456"
["sm_owner"]=>
string(9) "SMOWNERID"
["sm_owner_content"]=>
string(19) "123456798452"
["contact_owner"]=>
string(13) "Contact Owner"
["contact_owner_content"]=>
string(16) "Jane Doe"
}

Answer 1

try this code:
$NewArray = array();
foreach($OriginalArray as $value) {
$NewArray[] = array_merge($value,$NewArray);
}
or you can use array_merge_recursive

Answer 2

let $result = [];
foreach ($yourarray as $key => $value) {
$result = $value;
}
var_dump($result);

Answer 3

Here you go: How to Flatten a Multidimensional Array? – Barmar 23 mins ago
function flatten($array)
{
return array_reduce($array, function($acc, $item){
return array_merge($acc, is_array($item) ? flatten($item) : [$item]);
}, []);
}
// loop the individual fields
for ($i=0; $i<count($row_data); $i++) {
$newArray = flatten([$i => $response_row]);
}

Answer 4

Try something like this:
function flatten(array $array) : array
{
$newArray = [];
foreach ($array as $subArray) {
foreach ($subArray as $key => $value) {
$newArray[$key] = $value;
}
}
return $newArray;
}
