Scansione Array

[Ratatuia]

array_keys ti restituisce un array con le chiavi, quindi basta che poi ti metti a ciclare su quell'array per andare avanti nel parsare l'array...

ti posto un esempio di quello che faccio io:

$rooms = array_keys($data["planning"]);
            for ($j = 0; $j < count($rooms); $j++)
            {
                $this->room = $rooms[$j];
                for ($i = 1; $i <= count($data["period"]); $i++)
                {
                    $start = mktime(0,0,0,(int)$data["period"][$i]["from"]["month"],(int)$data["period"][$i]["from"]["day"],(int)$data["period"][$i]["from"]["year"]);
                    $end = mktime(0,0,0,(int)$data["period"][$i]["to"]["month"],(int)$data["period"][$i]["to"]["day"],(int)$data["period"][$i]["to"]["year"]);
                    $today = mktime(0,0,0,(int)date("n"),(int)date("j"),(int)date("Y"));
                    if (($start != -1 && $end != -1) && ($start <= $end) && ($start >= $today) && ($end >= $today))
                    {
                        $days = $end - $start;
                        $days = $this->seconds_to_days($days);
                        for ($n = 0; $n <= $days; $n++)
                        {
                            $week_day = $this->week_day($start + $this->day_to_seconds($n));
                            $date = $this->timestamp_to_date($start + $this->day_to_seconds($n));
                            $rates = array_keys($data["planning"][$rooms[$j]][$week_day]);
                            for ($k = 0; $k < count($rates); $k++)
                            {    
                                if (isset($data["planning"][$rooms[$j]][$week_day][$rates[$k]]["allocated"]))
                                    $allocated = $data["planning"][$rooms[$j]][$week_day][$rates[$k]]["allocated"];
                                if ($rates[$k] == 0)
                                    @$this->create_row($date,$rates[$k],$allocated);
                                else
                                {

                                        $single = $data["planning"][$rooms[$j]][$week_day][$rates[$k]]["single"];
                                    if (isset($data["planning"][$rooms[$j]][$week_day][$rates[$k]]["double"]))
                                        $double = $data["planning"][$rooms[$j]][$week_day][$rates[$k]]["double"];

                                    @$this->create_row($date,$rates[$k],$allocated,$price,$single,$double,$triple,$minstay,$maxstay,$cancellation);
                                }
