Question

I have config.php with this…

$dbhost = "localhost";

I want to be able to use the $dbhost variable inside a class.

User.class.php

include 'config.php';    
class User {
    private $dbhost = ???
    }

There’s a couple other questions like this, but they were for some other specific uses, and I guess it’s just a basic thing that I can’t really find anything else about it on the web.

UPDATE: Wow, thanks for all the help everybody. New to this site, but I might just stick around and give back where I can.

Answer 1

several ways I think.
First pass it to the class constructor:

include 'config.php';    
class User {         
    private $dbhost;

    function __construct($dbhost){
      $this->dbhost=$dbhost;
    }
}
$user= new User($dbhost);

Or use a setter:

include 'config.php';    
class User {         
    private $dbhost;

    function setDbhost($dbhost){
      $this->dbhost=$dbhost;
    }
}
$user= new User();
$user->setDbhost($dbhost);

Or using CONSTANTS:

define('DBHOST', 'localhost');
class User {         
    private $dbhost;

    function __construct(){
      $this->dbhost=DBHOST;
    }
}

OR using global:

include 'config.php';    
class User {         
    private $dbhost;

    public function __construct() {
    global $dbhost;
    $this->dbhost=$dbhost;
}
}
