Kode 

print_r($stats); = Array (
 16 => 5,
 17 => 21,
 18 => 5
)

PHP kode 

 $stats = $this->get("stats", null, array('visittime', 'count(*) cnt'));
 $new_stats = array()
 foreach($stats as $row) {
     $new_stats[$row['visittime']] = $row['cnt'];
 }
 
 $time_array = array('00', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24');
 foreach($time_array as $time){
     if(isset($new_stats[$time])) {
         echo '1';
     }
 }

PHP kode 

 print_r($stats); = Array ( [0] => Array ( [visittime] => 16 [cnt] => 5 ) [1] => Array ( [visittime] => 17 [cnt] => 21 ) [2] => Array ( [visittime] => 18 [cnt] => 5 ) )
     
 
     $time_array = array('00', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24');
     foreach($time_array as $time){    
 
 if($stats['visittime'] == $time){
 echo 1;
 }
     
     }

PHP kode 

 $cols = array('visittime', 'count(*) cnt');
     $stats = $this->get("stats", null, $cols);
     
     print_r($stats);
 // Array ( [0] => Array ( [visittime] => 16 [cnt] => 5 ) [1] => Array ( [visittime] => 17 [cnt] => 21 ) [2] => Array ( [visittime] => 18 [cnt] => 5 ) )
 
 Kan jeg omskrive mit array, uden at skulle rediger $stats ?
