This is my class for connecting to a database and it has a query method for looping through the results but it gives me this error:
Fatal error: Call to undefined method mysqli::fetch_assoc()
in C:\Apache24\htdocs\classes\DB.php on line 30
I know that the problem is in my query() method and I have tried using non static properties but the error continues.
<?php
class DB {
private static $db_name = "data_db";
private static $db_user = "root";
private static $db_pass = "root";
private static $db_host = "localhost";
private static $row;
private static $instance = null;
public static function get_instance() {
if(!isset(self::$instance))
self::$instance = new self;
return self::$instance;
}
//returns mysqli object.
private function __construct() {
$this->mysqli = new mysqli(self::$db_host, self::$db_user, self::$db_pass, self::$db_name);
}
public function __destruct() {
$this->mysqli->close();
}
public function query($query) {
if ($result = $this->mysqli->query($query)) {
if($result->num_rows > 1) {
$rows = array();
while ($item = $result->fetch_assoc()) {
$rows[] = $item;
}
} else {
$rows = $result->fetch_assoc();
}
return $rows;
}
}
