php - Break time into multiple times -

let's have array multiple instance of class:

class booking     {         public $status;         public $start_time;         public $end_time;     } 

• array[0] $status = true $start_time = 13:30 $end_time = 14:00
• array[1] $status = true $start_time = 14:30 $end_time = 17:30
• array[2] $status = true $start_time = 20:30 $end_time = 21:30
• array[3] $status = true $start_time = 22:00 $end_time = 23:30

how elaborate function given time, 12:00 , 23:00 generate array, multiple instances of same class, although this:

• array[0] $status = false $start_time = 12:00 $end_time = 13:30
• array[1] $status = true $start_time = 13:30 $end_time = 14:00
• array[2] $status = false $start_time = 14:00 $end_time = 14:30
• array[3] $status = true $start_time = 14:30 $end_time = 17:30
• array[4] $status = false $start_time = 17:30 $end_time = 20:30
• array[5] $status = true $start_time = 20:30 $end_time = 21:30
• array[6] $status = false $start_time = 21:30 $end_time = 22:00
• array[7] $status = true $start_time = 22:00 $end_time = 23:00

look in direction:

function generate($from, $till) {    $result = array();    $t = $from;    $status = true;    while($t <= $till)    {      $result[] = new booking($status, date('h:i', $t), date('h:i', $t+30*60));      $t = $t+30*60;      $status = !$status;    }    return $result; }
