i'd remove duplicate name. want keep 1 subject each day.

my code far:

$taken = array(); foreach($subject_list['choice'][0]["value"] $key =>$item ) {      if(!in_array($item['name'], $taken))      {         $taken[] = $item['name'];     }else      {         unset($flight_list['choice'][0]["value"][$key]);     }  } 

output of code above (which wrong):

array (     [choice] => array         (             [0] => array                 (                     [day] => monday                     [value] => array                         (                             [0] => array                                 (                                     [name] => bi                                     [time] => 10:00                                      [location] =>  b123                                 )                         )                 )              [1] => array                 (                     [day] => tuesday                     [value] => array                         (                             [0] => array                                 (                                     [name] => bi                                     [time] => 10:00                                      [location] =>  b123                                 )                             [1] => array                                 (                                     [name] => bi                                     [time] => 11:00                                      [location] =>  a123                                 )                         )                     )         ) ) 

anyone can me how can remove same class name @ tuesday.

if want keep first set of unique values in each value batch in terms of name, create temporary container that. if have pushed it, don't process anything, after gathering, overwrite batch using foreach & reference:

foreach($subject_list['choice'] &$items) {     $temp = array(); // temporary container current iteration     foreach($items['value'] $value) {         if(!isset($temp[$value['name']])) { // if new             $temp[$value['name']] = $value; // push batch using key name         }     }     $items['value'] = $temp; // apply unique value in end of batch }
