PHP Login and Registration Script with PDO and OOP

By
In my previous tutorial i have explained that how to use OOP in PDO, and now in this tutorial I'm going to explain a login and registration script using PDO and OOP, we already have a tutorial on this topic but that was for beginners with MySQL, and this one is with PDO and OOP, as PDO is improved extension it's must be used, i have used here new PHP 5.5 Password Hashing API function that creates strong password, for hashing password you have to use PHP 5.5 latest version of PHP and we will also see how to hash passsword using this functions and maintaining a user sessions using OOP so let's see the tutorial.

Create Database and table.

run the following sql code it will create database and table to store the users.

CREATE DATABASE `dblogin` ;
CREATE TABLE `dblogin`.`users` (
   `user_id` INT( 11 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,
   `user_name` VARCHAR( 255 ) NOT NULL ,
   `user_email` VARCHAR( 60 ) NOT NULL ,
   `user_pass` VARCHAR( 255 ) NOT NULL ,
    UNIQUE (`user_name`),
    UNIQUE (`user_email`)
) ENGINE = MYISAM ;

after creating a database and table we have to create a new file called 'dbconfig.php' which contains code for database connection within try/catch block for exception handling, and at the end of this file we need to include class.user.php class file.

dbconfig.php

create a new object called user and pass the database connection variable '$DB_con' in object's parameter to use database.
this file must be included at the beginning of all files except class file.

<?php

session_start();

$DB_host = "localhost";
$DB_user = "root";
$DB_pass = "";
$DB_name = "dblogin";

try
{
     $DB_con = new PDO("mysql:host={$DB_host};dbname={$DB_name}",$DB_user,$DB_pass);
     $DB_con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e)
{
     echo $e->getMessage();
}


include_once 'class.user.php';
$user = new USER($DB_con);



Password Hashing

There are 4 password hashing functions in PHP5.5, for that you have to use PHP5.5(WAMP2.5).
1. password_hash() – used to hash the password.
2. password_verify() – to verify a password with hashed password.
3. password_get_info() – Returns information of given hash.
4. password_needs_rehash() – Checks if the given hash matches the given options.

password_hash() and password_verify() are the important hashing functions.

password_hash() :
For hashing password we have to use password_hash() function, the first parameter is password and second parameter used to specify the algorithm to hash password.

<?php

     $password = "123456";
     $hash = password_hash($passwod, PASSWORD_DEFAULT);
     $hashed_password = "$2y$10$BBCpJxgPa8K.iw9ZporxzuW2Lt478RPUV/JFvKRHKzJhIwGhd1tpa";

     /*
     "123456" will become "$2y$10$BBCpJxgPa8K.iw9ZporxzuW2Lt478RPUV/JFvKRHKzJhIwGhd1tpa"
     */ 

?>

password_verify() :
For checking passwords, we have to use password_verify function, which checks a password string with a hashed password, then returns a boolean.

<?php

     $password = "123456";
     $hashed_password = "$2y$10$BBCpJxgPa8K.iw9ZporxzuW2Lt478RPUV/JFvKRHKzJhIwGhd1tpa";
     password_verify($password, $hashed_password);
          
     /*
      if the password match it will return true.
     */ 

?>

class.user.php

this file must be included at the end of 'dbconfig.php' file. and creating a new object of this class file in the 'dbconfig.php' file we can make use of database,
this is the main class file which contains register(),login(),is_loggedin(),redirect() functions to maintain users activity.
register() function register a new user with strong password hashing function.

<?php
class USER
{
    private $db;
 
    function __construct($DB_con)
    {
      $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 users(user_name,user_email,user_pass) 
                                                       VALUES(:uname, :umail, :upass)");
              
           $stmt->bindparam(":uname", $uname);
           $stmt->bindparam(":umail", $umail);
           $stmt->bindparam(":upass", $new_password);            
           $stmt->execute(); 
   
           return $stmt; 
       }
       catch(PDOException $e)
       {
           echo $e->getMessage();
       }    
    }
 
    public function login($uname,$umail,$upass)
    {
       try
       {
          $stmt = $this->db->prepare("SELECT * FROM users WHERE user_name=:uname OR user_email=:umail LIMIT 1");
          $stmt->execute(array(':uname'=>$uname, ':umail'=>$umail));
          $userRow=$stmt->fetch(PDO::FETCH_ASSOC);
          if($stmt->rowCount() > 0)
          {
             if(password_verify($upass, $userRow['user_pass']))
             {
                $_SESSION['user_session'] = $userRow['user_id'];
                return true;
             }
             else
             {
                return false;
             }
          }
       }
       catch(PDOException $e)
       {
           echo $e->getMessage();
       }
   }
 
   public function is_loggedin()
   {
      if(isset($_SESSION['user_session']))
      {
         return true;
      }
   }
 
   public function redirect($url)
   {
       header("Location: $url");
   }
 
   public function logout()
   {
        session_destroy();
        unset($_SESSION['user_session']);
        return true;
   }
}
?>






index.php/login page

index.php as login page which will take username or email id and password to access users home page if the details are wrong it will show appropriate message.

<?php
require_once 'dbconfig.php';

if($user->is_loggedin()!="")
{
 $user->redirect('home.php');
}

    1. Hi Hisham

      Alter "users" table and add new field as "joining_date" with "CURRENT_TIMESTAMP"

      or select database then run following sql code inside phpMyAdmin

      ALTER TABLE `users` ADD `joining_date` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ;

    1. HI Natasha

      it's easy to implement forget password module inside this script...
      create new file as forget.php and add simple form with email input box then check user, validate email and create encrypted string to reset password with userid within this file use mail() function or PHPMailer to send reset password link to the users mail, then create new file as reset.php in this file you can set new password for the user..

      I'll make a tutorial it for soon :)

  11. Some questions i am wondering about, why start the user class on every page since you are including the db_config on every page, and at the same time you will be defining only one instance of a class. I thought the benefits of OOP is that you can have many instances of the same class. Like you can have $user_register = new user and $user_profile = new user. Two different instances of using the user class in two scenarios. Also why not create a database class when you are doing OOP? Have methods like connect(), query(), execute(). For me this seems like procedural programming mixed in with OOP.

    1. hi avean...

      yes we can create multiple objects for one class as you said user_reg, user_profile but i have created one class for user and one object for that class and using user object we can access all the functions of user class, so i have user here only one object to access all user functions , and PDO is improved extension we it has prepare(), execute() functions that i have used here ....

  13. Fabulous. Thank you.
    I have been reading and playing with this script all day!
    One thing I would like to ask - using sessions for checking the log in status... Is this secure ? I understand if over a https protocol reasonably secure, but each time the script checks log in it only looks for the session.
    If, for example, a user were to be banned, when would his session expire, as there does not seem to be an expiry on the session.
    Great work, thank you!

    1. Hey Kevin...

      This is simple script using PDO and OOP
      you can logged in only verified users and active users for that you have to register email verified users and when user is active status they can log in and banned users can not log in, and you can also set time for user inactivity , if there is no user activity their session automatically expires after defined time for inactivity...

      Hope this helps...

    3. hi giri,
      you don't need to use https with this script, it works with both protocol http or https, but if you are facing login problem then there's must be some warning or error, so tell me what kind of exception you are facing ?

    4. found the problem. there was a problem with my sql table. my password line was like `user_pass` VARCHAR( 15 ) NOT NULL ,. 15 is not enough for hashed password so a corrected it to `user_pass` VARCHAR( 100 ) NOT NULL , now everything's fine. thank you:-)

    1. hello harry,
      if the sign up information is not registered then there's must be some error or exception, so check your mysql table , insert query and all the fields as well , if you made some changes in this script then you must check it with the original one, hence this is working script ? or check that which php version you are using is it 5.5 or lower i have given both script in the downloads zip file, you are working on 5.5 or lower ?

  21. Please i am confused, where should this file be or is it incorporated in any of the other .php files.password_hash() and password_verify() you said they are important but you did not elaborate how to use it, men i am going crazy help me out please.

    Replies
    1. hello harry,
      there is no specific file for these two functions "password_hash() and password_verify()", these are new password hashing functions for PHP 5.5 not for lower PHP versions. and how to use these functions i have explained in this tutorial , so to use these functions you have to use PHP 5.5 version .

    1. hi harry.
      i replied you in your previous comment, again I'm telling you that "password_hash()" is password hashing function and works with PHP5.5 , if it will not write data to database then check insert query in register function or check user_pass fields varchar size in mysql table.

  33. Hi Pradeep. Thank you, this is the best explained script I've seen in a long time. You're a good teacher :)

    If you can, please help me with one small issue.

    The email is correctly sent, and the link (to activate account) looks like this:
    mydomain.com/verify.php?id=MTUz&code=c74f01c3ea3edf807b21fc4ea28a41cb

    I have checked that user does indeed exist in tbl_users and the above CODE is the same.

    I think the issue is with the ID: ?id=MTUz, because when you click the link, it says sorry! Account not found.

    Please help when you can.

    Kind regards.

  36. Hello Pradeep Khodke. Your tutorial is informative and has insights on procedural and OOP-based programming. Let me add though that in password hashing using the password_verify() function, be careful not to enclose your password hash containing the Dollar character ($)in double quotes because PHP will partly interpret the hash as a variable and will throw unexpected results. Always use single quotes.

Registration works without a hitch, can see the user in mysql. however when logging in via index.php - the account is accepted but am not redirectd to home.php . browsing directly to home.php sends me back to index.php . Seems to be a session issue - so tried in private browsing, no luck. no changes to script.

    I am assuming it is the php version on my server which is causing the issue, because it lets me fill out the form, and doesn't display any database erors at first. It just goes to this page when I hit submit.

  56. Hi, Thanks for this tutorial it's just what I was looking for. Most others are really out of date and I find your approach very simple and easy to understand. I especially like how you explain each block of code (great for newbies like me!).

    Just one thing I noticed - when I downloaded your script files - in class.user.php (line 70ish) the function is called `public function doLogout()`. However here on the tutorial page it's called `public function logout()`. This had me puzzled for a while as I was following your tutorial here and had half the code written, I then decided to download the rest of the files, and my files didn't match! My logour wouldn't work and kept throwing an unknown function error.

    No big deal, if anybody else is reading this make sure ALL your functions are named the same or you will have issues like I did

    Thanks again, can't wait for your other tutorials :)

  66. This looks great! It worked fine for me, but I have a concern: It seems there are additional measures you could/should take to prevent hacking, such as via SQL injection. I see you're using DBO::prepare, which helps to prevent SQL injection, according to some references [1][2] this may not be enough. In [2], author recommends also setting the following attribute:
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
    In your code, you use:
    $this->conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    What measures are you taking (besides DBO::prepare) to prevent hacking?
