Map two arrays key and value to create json object in 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);

And what have you done to try and achieve this, so far? We're not here to do your job for you. — Marc B

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"
  }
}
