How to pre fill an array with missings keys?

[beginnerForPHP]

$test['0000'] = [2 =>'tes000'];

$test['1111'] = [0=>'tes1', 1=>'tes11', 2 =>'tes111'];

$test['2222'] = [0=>'tes2', 1=>'tes22', 2 =>'tes333'];

How do i prefill the $test array with missing keys  with value as 'NIL' to get the result as :

$test['0000'] = [0=>'NIL', 1=>'NIL', 2 =>'tes000'];

$test['1111'] = [0=>'tes1', 1=>'tes11', 2 =>'tes111'];

$test['2222'] = [0=>'tes2', 1=>'tes22', 2 =>'tes333'];

Looks like you already did that. Perhaps you need to better explain what you are trying to do and post some actual code. Also, when you post code use the code icon (<>) in the top menu and specify PHP.

$test =  [ '0000' => [2 =>'tes000'],
           '1111' => [0=>'tes1', 1=>'tes11', 2 =>'tes111'],
           '2222' => [0=>'tes2', 2 =>'tes333']
         ] ;
         
$test = array_map( function($v) {
                      return array_replace(array_fill_keys(range(0,2), 'NIL'), $v);
                   }
                   , $test);
                   
echo '<pre>' . print_r($test, 1) . '</pre>';

Array
(
    [0000] => Array
        (
            [0] => NIL
            [1] => NIL
            [2] => tes000
        )

    [1111] => Array
        (
            [0] => tes1
            [1] => tes11
            [2] => tes111
        )

    [2222] => Array
        (
            [0] => tes2
            [1] => NIL
            [2] => tes333
        )

@BarandHow do i use the range() in case if my array is as follows with time range  or is there any other alternative as time difference can be based on hour and half-hour. In example it is based on every hour.

Use a DatePeriod() object to generate the NIL array.

I'd show the code but I am having difficulty processing that image of your data in my test code.

(Hint: in future, use var_export() with arrays)
