Question

I can’t use the PDO class methods from my own pdo_connection class, with or without extends PDO, it doesn’t work properly.

Class pdo_connection { 
//connection create 
    private $dbhost = "127.0.0.1"; 
    private $dbname = "db"; 
    private $dbuser = "user"; 
    private $dbpass = "pass"; 
    public function __construct() { 
        return $db = new PDO('mysql:host=' . $this->dbhost . ';dbname=' . $this->dbname, $this->dbuser, $this->dbpass); 
    } 
}

And then when I create the object:

require("api/pdo.connection.class.php"); 
$db = new pdo_connection(); 
$db->exec("SET NAMES utf8");  

I can’t use exec, because is not a method of pdo_connection class, but I want to use the methods of PDO that is created in the pdo_connection class.

If you want to be able to use pdo_connection like that, you will have to extend PDO.

Example:

class db extends PDO {

Then, inside that class, in __construct, use parent::__construct:

parent::__construct('mysql:host=' . $this->dbhost . ';dbname=' . $this->dbname, $this->dbuser, $this->dbpass);

This is the class that I made that uses that method: [link]

Usage:

include_once 'db.php';
$db = new db('user');
// Do stuff with $db
