Question

I'm trying to connect to my database but it won't connect. I tried but won't connect. the error I'm getting is Parse error: syntax error, unexpected 'connect' (T_STRING) in C:\htdocs\www\dating\index.php on line 3. I called the tried new Database connect(); and tried connect(); I get this message Fatal error: Call to undefined function connect() in C:\htdocs\www\dating\index.php on line 3. What's wrong?
class Database{
private $db_host = "localhost";
private $db_user = "123346";
private $db_pass = "12345";
private $db_name = "1234";
public $conn;
// Create connection
public function connect(){
if(!isset($this->conn)){
$this->conn = new mysqli_connect($this->db_host,$this->db_user,$this->pass,$this->db_name);
if($this->conn){
$this->conn = true;
return true;
}else{
$this->conn = false;
return false;
}
}
}
public function disconnect(){
if(isset($this->conn)){
if(mysqli_close($this->conn)){
$this->myconn = false;
echo "connection closed";
return true;
} else{
echo "failed to close connection";
return false;
}
}else{
echo "no connection prescent";
}
}
}

include("functions/connect.php");
$db = new Database("localhost", "12345", "1234", "123");

/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT id, username FROM users ORDER by ID DESC ";
if ($result = $db->query($query)) {
/* fetch object array */
while ($row = $result->fetch_row()) {
printf ("%s (%s)\n", $row[0], $row[1]);
}

Please change this line
$this->conn = new mysqli_connect($this->db_host,$this->db_user,$this->pass,$this->db_name);
to this
$this->conn = new mysqli_connect($this->db_host,$this->db_user,$this->db_pass,$this->db_name);
You will notice you used $this->pass but it should be $this->db_pass.
To call the function of Database class you have to write your code like this;
<?php
include("functions/connect.php");
$db_conn = new Database();
if($db_conn->connect()) {
echo "Database connected";
}
