Is there a better alternative way to reduce the below code?

[beginnerForPHP]

<?php
$test['0000'] = ['address' =>'tes0'];
$test['1111'] = ['id'=>'tes1', 'name'=>'tes11', 'address' =>'tes111'];
$test['2222'] = ['id'=>'tes2', 'name'=>'tes22', 'address' =>'tes222'];
$test['3333'] = ['id'=>'tes3', 'name'=>'tes33'];

$keys = [];
foreach ($test as $t) {
    $keys = array_merge($keys, array_keys($t));
}
$keys = array_fill_keys(array_unique($keys), 'NIL');

foreach ($test as &$t) {
    $t = array_merge($keys, $t);
}
print_r($test);

Is there a more better way to reduce the above code to fill in the missing keys and get the expected result as:

Array
(
    [0000] => Array
        (
            [id] => NIL
            [name] => NIL           
            [address] => tes0
        )

    [1111] => Array
        (

            [id] => tes1
            [name] => tes11
            [address] => tes111
        )

    [2222] => Array
        (

            [id] => tes2
            [name] => tes22
            [address] => tes222
           
        )

    [3333] => Array
        (

            [id] => tes3
            [name] => tes33
            [address] => NIL
         
        )

)

<?php
$test['0000'] = ['address' =>'tes0'];
$test['1111'] = ['id'=>'tes1', 'name'=>'tes11', 'address' =>'tes111'];
$test['2222'] = ['id'=>'tes2', 'name'=>'tes22', 'address' =>'tes222'];
$test['3333'] = ['id'=>'tes3', 'name'=>'tes33'];

$nil = ['id'=>'NIL', 'name'=>'NIL', 'address' =>'NIL'];

$test = array_map( function($v) use ($nil) {
                      return array_replace($nil, $v);
                   }
                   , $test);

PS Definite feeling of deja vu here
