Hi I'm trying to use the functions/methods of one class inside another, however I keep getting errors and I don't understand this...
for example;
class DB {
private $host;
private $user;
private $pass;
private $database;
public function __construct($host, $user, $pass, $database) {
...
}
public function query($sql) {
...
}
}
$db = new DB;
class Permissions {
global $db;
public function update($user_id) {
$this->db->query("UPDATE `users` SET `user_name` = 'Dom'....");
}
}
It probably can't connect to the DB... Unless the DB class uses your login credentials as default.
$db = new DB('localhost', 'youruser', 'yourpass', 'yourdb');might do the trick, although this solution is not recommended.
thats not the problem, I cut bits out of the code to make it clearer. DB connection works. Just trying to access class methods outside of the class.
"syntax error, unexpected T_GLOBAL, expecting T_FUNCTION"
"Can't use function return value in write context"
Apparantly global is not allowed within a class definition.
I think I found a solution and that is to reference the other class llike so
Class {
public $db;
public function __construct() {
$this->db = &new DB;
}
}This works with no problems, thanks anyways.
