thanks for the great insights dude.. I'll go ahead and sort this one out hopefully

I don't know why it won't work.. as the topic titles says that I am trying to pass a mysqli object to a property in another class but it keeps me getting an error. here's the code for the mysqli object that i want to pass to another class class ConnectMe2Db { public $dbname = 'somedatabase'; public $dbuname = 'root'; public $dbpass = ''; public $dbhost = 'localhost'; function __construct() { $mysqli = new mysqli($this->dbhost,$this->dbuname,$this->dbpass,$this->dbname) or die ('ERROR: '.$mysqli->connect_errno); return $mysqli; } # OTHER CODES... } and here is the class that i want the Mysqli object to pass to: class DatabaseUsers { private $dbconnection; function __construct() { $this->dbconnection = new ConnectMe2Db();#mysqli object will be passed to this attribute '$dbconnection' } public function session($username, $password) { $UserName = mysqli_real_escape_string($this->dbconnection,$username); $Password = mysqli_real_escape_string($this->dbconnection,md5($password)); $querry = "SELECT * FROM trakingsystem.login WHERE username='$username' and password='$password'"; $result = mysqli_query($this->dbconnection,$querry) or die (mysqli_error($this->dbconnection)); $count = mysqli_num_rows($result); $row = mysqli_fetch_array($result); if ($count > 0) { #some code here } } #some other code here } and this outputs 4 errors: #outputs 2 of these: Warning: mysqli_real_escape_string() expects parameter 1 to be mysqli and some mysqli_query() expects parameter 1 to be mysqli mysqli_error() expects parameter 1 to be mysqli is there something wrong with the logic that I've made? please help thanks
