php - Displaying a day of bookings for a room -


i working on school room booking system having trouble outputting bookings.

public function displayroombyday() {     $query = db::getinstance()->query("select b.roomid, b.period, r.roomname, b.bookingdate, b.bookingid booking b inner join room r on b.roomid = r.roomid bookingdate = '2016-11-03' , b.roomid=1 order b.period"); //inner join      $count = $query->count();     $freecount = 0;         for($periods=1;$periods<=6;$periods++) {             for($x=0;$x<$count-1;$x++) {                 $outputted=false;                 $freecount=0;                 {                                             if($query->results()[$x]->period == $periods) {                         echo $query->results()[$x]->period . '<br>';                         $outputted=true;                     } else {                         echo 'free' . '<br>';                         $freecount = 1;                     }                 } while($outputted = false , $freecount=0);             }         } }

this function use output data. sql query returns 2 items, booking in period 5 , booking in period 1 (i have tested through phpmyadmin). trying use nested loops , while loop loop through periods available in day (6). there loop through 2 bookings sql query returns code:

for($x=0;$x<$count-1;$x++) {     $outputted=false;     $freecount=0;     {                                 if($query->results()[$x]->period == $periods) {             echo $query->results()[$x]->period . '<br>';             $outputted=true;         } else {             echo 'free' . '<br>';             $freecount = 1;         }     } while($outputted = false , $freecount=0); }

however when run page, 1 free free free free free, when trying 1 free free free free 5 when bookings are.

your logic complicated task. can simplify like:

public function displayroombyday() {     $query = db::getinstance()->query("         select b.roomid,                b.period,                r.roomname,                b.bookingdate,                b.bookingid         booking b         inner join room r             on b.roomid = r.roomid         bookingdate = '2016-11-03'           , b.roomid=1 order b.period"); //inner join      $results = array_reduce($query->results(), function ($carry, $item) {         $carry[$item->period] = $item;         return $carry;     }, []);      $periods = range(1, 6);      foreach ($periods $period) {         if (isset($results[$period]) {             echo $period . '<br />';         } else {             echo 'free' . '<br />';         }     } }

i think that's need.
