PHP设置值的类

Question

我有两个PHP类（DBOperations.php和functions.php）。现在我想从functions.php类的DBOperations.php类中设置一个值。

class DBOperations{ 

    private $host = 'localhost'; 
    private $user = 'u'; 
    public $database; 
    private $pass = 'p'; 
    private $conn; 

public function __construct() { 



    $this -> conn = new PDO("mysql:host=".$this -> host.";dbname=".$this -> database, $this -> user, $this -> pass); 

    } 
public function doMagic() { 
//running mysql queries here 
} 

和functions.php中：

require_once 'DBOperations.php'; 

class Functions{ 

private $db; 

public function __construct() { 

     $this -> db = new DBOperations(); 
} 
public function doThings($variable) { 

    $db = $this -> db; 
    //here I want to set the value $database from the DBOperations class to //$variable 

有人可以帮助NME了呢？

Answer 1

您可以通过像

public function doThings($variable) { 

    $db = $this -> db; 
    $this->db->database = 'dbname'; 
    // same for all variables if they are public 
}
