PHP: manipulate array making value as key recursively - php

Question

I got this array:
array:2 [▼
0 => array:1 [▼
0 => array:7 [▼
"id" => "1"
"producer" => "Samsung"
"model" => "LE22B541C4W"
"category" => "1"
"production_date" => "2009-05-08"
"status" => "Discontinued"
"type" => "LCD"
]
]
1 => array:1 [▼
0 => array:7 [▼
"id" => "2"
"producer" => "Samsung"
"model" => "P24FHD"
"category" => "1"
"production_date" => "0000-00-00"
"status" => "Discontinued"
"type" => "LCD"
]
]
[...]
]
I would like to take the "ID" value of each array and make as primary key and remove the useless keys like this
array:2 [
1 => array:7 [
"id" => "1"
"producer" => "Samsung"
"model" => "LE22B541C4W"
"category" => "1"
"production_date" => "2009-05-08"
"status" => "Discontinued"
"type" => "LCD"
]
2 => array:7 [
[...]
By now I'm just populate the array using this simple query and a for loop:
foreach ($compatibility as $compElement) {
$sql = "SELECT * FROM product WHERE ID = '$compElement';";
$em = $this->getDoctrine()->getManager();
$stmt = $em->getConnection()->prepare($sql);
$stmt->execute();
$thisElement = $stmt->fetchAll();
$compArray[] = $thisElement;
}

You can do something like this if you don't want to change how you populate your array:
$result = call_user_func_array(
'array_merge_recursive',
$array
);
Output
array(2) {
[0]=>
array(7) {
["id"]=>
string(1) "1"
["producer"]=>
string(7) "Samsung"
["model"]=>
string(11) "LE22B541C4W"
["category"]=>
string(1) "1"
["production_date"]=>
string(10) "2009-05-08"
["status"]=>
string(12) "Discontinued"
["type"]=>
string(3) "LCD"
}
[1]=>
array(7) {
["id"]=>
string(1) "2"
["producer"]=>
string(7) "Samsung"
["model"]=>
string(6) "P24FHD"
["category"]=>
string(1) "1"
["production_date"]=>
string(10) "0000-00-00"
["status"]=>
string(12) "Discontinued"
["type"]=>
string(3) "LCD"
}
}
