php - How do I access each value in array? -

i have attempted numerous times trying access each value in array. array contains database results retrieved select query.

$query = db::getinstance()->query("select orderstatus customerorders");                      foreach ($query->results() $orderered) {     $result_array = array($orderered);  //print_r($result_array);  $orderdata = array_map(function ($object) { return $object->orderstatus; },                $result_array);    $test = json_decode(json_encode($result_array), true);      $orvalue = serialize($test);     $orvalue2 = unserialize($orvalue);     $ordervaluenew = call_user_func_array('array_merge', $orvalue2);     print_r($ordervaluenew);//debug    }//close foreach loop 

result prints are:

array ( [orderstatus] => 0 )  array ( [orderstatus] => 0 )  array ( [orderstatus] => 0 )  array ( [orderstatus] => 1 )  array ( [orderstatus] => 1 )  

what you're doing should work retrieve each row, if want access orderstatus value, can result array:

 foreach ($result_array $resultrow) {     echo $resultrow['orderstatus'];  } 

that should work, if that's mean. if want access orderstatus value in first loop, can refer $row['orderstatus']. or, if select * in query , want go through values query, can make loop foreach ($row $column => value) { ... }
