Map two arrays key and value to create json object in php - php

Question

Hi guys I'm trying to map key with values in PHP to create JSON object, can someone help please.
My keys array:
[
"ID",
"NAME",
"PRICE",
"TYPE"
]
My values array:
[
[
"1",
"Chicken Royal",
"25",
"Sandwich"
],
[
"2",
"Beef Whopper",
"30",
"Burger"
],
[
"3",
"Beef Royal",
"30",
"Burger"
]
]
What I'm looking for is:
[
"ID":"1",
"NAME":"Chicken Royal",
"PRICE":"25",
"TYPE":"Sandwich"
]
I've used this function
$result = array_map( function($k,$v) { return array('column' => $k,'value' => $v); }, array_keys($columnNames),$values);

With array_combine you can creates an array by using one array for keys and another for its values.
$keys = [
"ID",
"NAME",
"PRICE",
"TYPE"
];
$values = [
[
"1",
"Chicken Royal",
"25",
"Sandwich"
],
[
"2",
"Beef Whopper",
"30",
"Burger"
],
[
"3",
"Beef Royal",
"30",
"Burger"
]
];
$results = array_map(function($values) use ($keys) {
return array_combine($keys, $values);
}, $values);
var_dump($results);
Output:
array(3) {
[0]=>
array(4) {
["ID"]=>
string(1) "1"
["NAME"]=>
string(13) "Chicken Royal"
["PRICE"]=>
string(2) "25"
["TYPE"]=>
string(8) "Sandwich"
}
[1]=>
array(4) {
["ID"]=>
string(1) "2"
["NAME"]=>
string(12) "Beef Whopper"
["PRICE"]=>
string(2) "30"
["TYPE"]=>
string(6) "Burger"
}
[2]=>
array(4) {
["ID"]=>
string(1) "3"
["NAME"]=>
string(10) "Beef Royal"
["PRICE"]=>
string(2) "30"
["TYPE"]=>
string(6) "Burger"
}
}
