  2. Hi, I dont know what title that is more suitable for this topic but I will try to explain it as well as I can I have a class that I will use it for interacting with database I facing a problem when calling the method with "::" assign here is the code <?php class Crud { protected $data; protected $db; protected $query; protected static $action; protected static $instance = null; protected static $columns = []; protected $table; public function __construct() { $this->db = new mysqli('localhost', 'root', '', 'bahan_belajar'); if (!$this->db) { // throw new Exception("Koneksi error", $this->db->errno); echo "error"; } return $this; } public static function getInstance() { if (self::$instance === null) { self::$instance = new self; } return self::$instance; } public function select() { if (empty(func_get_args())) { // $this->columns = "*"; self::$columns = "*"; } else { if (is_array(func_get_args())) { // self::columns = join(', ', func_get_args()); self::$columns = join(', ', func_get_args()); } else { // self::columns = func_get_args(); self::$columns = func_get_args(); } } self::$action = "SELECT"; return $this; } public function from($tableName) { $this->table = ' FROM ' . $tableName; return $this; } public function get($getName = 'object') { $this->query = self::$action . ' ' . self::$columns . ' ' . $this->table; switch ($getName) { case 'object': $this->data = $this->db->query($this->query)->fetch_object(); break; case 'array': $this->data = $this->db->query($this->query)->fetch_array(); break; case 'count': $this->data = $this->db->query($this->query)->num_rows; break; } return $this->data; } } $chat = Crud::getInstance()->select('nama', 'teks')->from('chat')->get(); echo '<pre>'; print_r($chat); echo '</pre>'; actually this code was work fine when I put getInstance() method in the first method but how to make it work without putting that method? example : $chat = Crud::select('nama', 'teks')->from('chat')->get(); this will produce Fatal error like : Fatal error: Uncaught Error: Using $this when not in object context in C:\xampp\htdocs\bahan_belajar\chat\classes.php:47 Stack trace: #0 C:\xampp\htdocs\bahan_belajar\chat\classes.php(74): Crud::select('nama', 'teks') #1 {main} thrown in C:\xampp\htdocs\bahan_belajar\chat\classes.php on line 47 I just want to call it with "::" assign and not with "->" assign in first the method please help me how to solve this also I am sorry for my bad code structures thanks in advance
