How do I initialize a PHP class by passing a parameter at the same time. Same as PDO that is initialized by passing parameters as data for the connection to the database.
In my case I want to simply pass an ID on startup. Ex:
$user = new User($id);
And after passing the parameter using the construct function to load all information from that user, without the need to call some function manually for such an action.
Use a builder :
class User {
protected $id;
public $dados;
public function __construct($id) {
$this->id = $id; // aqui já tens o teu id
// echo $this->id; // vai imprimir 4 e podes fazer o que quiseres com ele ao longo dos metodos/atributos desta instância
// aceder à base de dados, SELECT * FROM users WHERE id = $id, 4 neste caso
// depois já terás os dados que queres acerca do utilizador
$this->dados = array('id' => 4, 'nome' => 'Miguel', 'email' => '[email protected]');
}
}
$u = new User(4);
echo $u->dados['email']; // [email protected]
In this case $dados is just an example of a return of the database information
