Convert flat, associative array into indexed 2d array with associative rows

Question

I have an array like this

[
    123456 => 'John Doe'
    654321 => 'Doe John'
]

I want to change the array key (123456 and 654321) into an index (0,1,2,3,....,n) and save it into value, the expected result looks like this

array(
    0 => array(
        'name' => 'John Doe',
        'code' => 123456.
    ),
    1 => array(
        'name' => 'Doe John',
        'code' => 654321.
    ),
)

this is the code i have tried, i have only gotten so far

$thearray= array_map(function ($value, $key) {
                return $key;
            }, $thearray, array_keys($thearray));

Answer 1

Use the foreach

$pemeriksa = [
    123456 => 'John Doe',
    654321 => 'Doe John'
];

$newArray = [];
foreach ($pemeriksa as $key => $value) {
    $newArray[] = ["name" => $value , "code" => $key];
}
print_r($newArray);

Answer 2

Within a foreach loop, define the keys and values using the keyname that you wish to see in the resultant rows, Then call compact() within the loops body before pushing the new row's data into the result array.

Code: (Demo)

$result = [];
foreach ($thearray as $code => $name) {
    $result[] = compact(['name', 'code']);
}
var_export($result);

Your functional-style programming can be fixed up like this:

Code: (Demo)

var_export(
    array_map(
        fn($name, $code) => compact(['name', 'code']),
        $thearray,
        array_keys($thearray)
    )
);
