Question

I try to create a list with nested foreach loop. First loop is looping some numbers, second loop is looping dates. I want to write one number to one date. So there is a another function to check that. But the result is numbers writes on dates multiple times.

Out is something like that :

number 5 is on 2013.01.15;
number 5 is on 2013.01.16;
number 5 is on 2013.01.17;
number 6 is on 2013.01.15;
number 6 is on 2013.01.17;

The code :

function create_event($numbers,$available_dates) {
  foreach($numbers as $number) {
    foreach($avaliable_dates as $av_date) {

      $date_check= dateCheck($av_date,$number);

      if ($date_check == 0) {
        echo "number ".$number." is on ".$av_date;
        break;
      } else {
        $send_again[] = $number;
      }

    }
  }
  create_event($send_again,$avaliable_dates);
}

I think inside loop is not break.

Can you check something like this:

function create_event($numbers,$available_dates) {
    foreach ($numbers as $number) {
        foreach ($available_dates as &$av_date) {
            if (dateCheck($av_date, $number) == 0) {
                unset($av_date);
                break;
            }
        }
    }
}
