<?php

$this->db = $DB_con;

public function register($fname,$lname,$uname,$umail,$upass)
{
try
{
$new_password = password_hash($upass, PASSWORD_DEFAULT);

$stmt = $this->db->prepare("INSERT INTO `users1`(`user_name`,`user_email`,`user_pass`)
VALUES(:uname, :umail, :upass)");

$stmt->bindparam(":uname", $uname);
$stmt->bindparam(":umail", $umail);

$userRow=$stmt->fetch(PDO::FETCH_ASSOC);
