php generate sequence based on array value

I want this array

$passengers = array(
            'adult' => 2,
            'child' => 1,
            'infant' => 1
        );

to change like this. Create a sequence based on number of persons.

Array(
[adult] => Array(
        [0] => 1
        [1] => 2
    )

[child] => Array(
        [0] => 3
    )

[infant] => Array(
        [0] => 4
    )

)

I'm stuck with this code

        $seq=1;
        foreach($passengers as $paxKey => $paxVal){

            if($paxVal>1){
                $pax[$paxKey][] = $seq;
                $seq = $seq+$paxVal;
            }else{
                $seq=$paxVal+$seq;
                $pax[$paxKey][] = $seq;
            }
        }

Any assistance is highly appreciated.

$result = [];
$counter = 1;
foreach($passengers as $key=>$value)
{
  for($i=0;$i<$value;$i++)
  {
      $result[$key][] = $counter;
      $counter++;
  }   
}
print_r($result);

Try this:

$pax = [];
$seq = 1;

foreach($passengers as $key => $val){
  while($val--) {
   $pax[$key][] = $seq;
   $seq++;
 }
}

There are two cycles: the first one cycles the passengers, the second one creates as many elements as you need for each (kind of?) passenger.
