How to add dynamic keys in PHP array

Question

I don't have a glue how to solve my problem. I want to produce an array like this one:

$days = array( 
            02=>array(NULL,'request_day'), 
            03=>array(NULL,'request_day'), 
            04=>array(NULL,'request_day'), 
            05=>array(NULL,'request_day'), 
        );

I need this to display the requested days on a calendar. Now I deal with a problem that I'm not able to generate dynamic keys (the the keys 02/03/04/05 as stated above).

My code looks like that:

    $days = array();
    $array_framework = array(NULL,'request_day');
    foreach ( $period as $dt )
    {
        echo $dt->format("d");
        $blub = $dt->format("d");
        $days[] = array($blub=>$array_framework);
    }

$period is an array which represent the days between two dates, and $blub prints out one day after another.

Daniel is right, use array_push, right now you made 3-dimensional array. — Goran Lepur

Remove $days[] = array($blub=>$array_framework); and use:

$days[$blub] = $array_framework;

thanks but that don't really works. it produces

Array ( [04] => Array ( [0] => Array ( [0] => [1] => request_day ) ) [05] => Array ( [0] => Array ( [0] => [1] => request_day ) ) [06] => Array ( [0] => Array ( [0] => [1] => request_day ) ) [07] => Array ( [0] => Array ( [0] => [1] => request_day ) ) )

ok thanks. that array is now what it should be but the result is not as expected... but it's not the array's fault

I think that this is what you want to do. If you have problems with the array keys being turned from strings (e.g. 03) into integers (e.g. 3) then cast the array key to a string.

$days = array();
$array_framework = array(NULL,'request_day');
foreach ( $period as $dt )
{
    $days[$dt->format("d")] = $array_framework;
}

That's what you wanted. You can ignore the 0 and 1 keys in the sub-arrays.

To verify that add a print_r($array_framework) in the line after you declare it.
