php - Array to string conversion smarty template -

hello have array string conversion erro code:

index.php:

code:

$hoarr = array(1,2,3);  foreach ($hoarr $hid) {      $mysqli = mysqli_connect("localhost", "root", "", "zabbixtest");      if (!$mysqli) {          die("connection failed: " . mysqli_connect_error());      }      $sql = "select errors_from hosts hostid = '$hid'";      $re = mysqli_query($mysqli, $sql);      while ($row = mysqli_fetch_assoc($re)) {          $query_times[] = $row['errors_from'];        }        mysqli_free_result($re);      mysqli_close($mysqli);    }   $smarty->assign('query_times',$query_times); 

and index.tpl:

code:

<p>{$query_times}</p> 

i have no idea whats wrong it..

you try assign array $smarty->assign can assign string.

use instead:

$query_string = implode ( "," , $query_times ); $smarty->assign('query_times',$query_string);
