I'm just getting started with OOP and I'm having trouble connecting to the database.
I made a class that would allowed to connect to the database but I had to use 'global $mysqli' in every method to avoid the non-object errors.
Now, I'm experimenting with a singleton pattern but I have no idea how to access the database connection from another class.
Database class:
PHP Code:
class database{
private $mysqli;
private function __construct(){
$this->mysqli = new mysqli($this->host, $this->user, $this->pass, $this->name);
}
public static function getInstance(){
if(is_null(database::$instance)){
database::$instance = new database();
}
return database::$instance;
}
}
New class where it all goes wrong:
PHP Code:
class p {
public function select($sql){
$query = $mysqli->query($sql);
}
}
It works fine outside the classes using:
$db = database::getInstance();
I'd really appreciate it if someone could point me in the right direction.
