Php Login Page Example

PHP Programming

Are you looking for a PHP login page example? Well, you’ve come to the right place! As a web developer who has worked extensively with PHP, I can assure you that creating a login page in PHP is not only essential for user authentication but also a great way to enhance the security of your website.

Before we dive into the technical details, let’s talk about why having a login page is important. As websites become more interactive and personalized, it has become necessary to restrict access to certain parts of a website. A login page allows you to control who can access sensitive information or perform specific actions on your website.

In this article, I will walk you through the process of creating a PHP login page step by step. We will cover everything from setting up the HTML form to validating user credentials and implementing proper security measures.

Getting Started

First, let’s start with the HTML form. Create a new PHP file and add the following code:

<form method="POST" action="login.php">
<label for="username">Username:</label>
<input type="text" id="username" name="username" required>

<label for="password">Password:</label>
<input type="password" id="password" name="password" required>

<input type="submit" value="Log In">

Make sure to replace the action attribute of the form with the filename of your PHP script, which we will create next.

Creating the PHP Script

Now, let’s create the PHP script that will handle the form submission and validate the user’s credentials. Create a new PHP file, name it “login.php”, and add the following code:

// Assuming you have a database connection established

// Retrieve user credentials from the form
$username = $_POST['username'];
$password = $_POST['password'];

// Validate user credentials
if ($username === 'myusername' && $password === 'mypassword') {
// Redirect the user to the dashboard or home page
header('Location: dashboard.php');
} else {
echo 'Invalid username or password. Please try again.';

Make sure to replace “myusername” and “mypassword” with your own username and password for testing purposes. In a real-world scenario, you would retrieve the credentials from a database and compare them to ensure proper authentication.

Securing the Login Page

Now that we have a basic login page set up, it’s important to implement some security measures to protect against common vulnerabilities.

One way to enhance security is by using password hashing. Storing plain-text passwords in your database is a huge security risk. Instead, you should hash the user’s password before storing it and compare the hashed values for authentication. PHP provides the password_hash() and password_verify() functions for this purpose.

Another crucial security measure is to prevent brute force attacks. Limiting the number of failed login attempts within a certain time frame can help protect against automated guessing of passwords. You can achieve this by keeping track of failed login attempts in a session variable and blocking further attempts after a certain threshold is reached.


Creating a login page in PHP is an essential part of building a secure and user-friendly website. By following the steps outlined in this article, you can create a functional login page that validates user credentials and enhances the security of your website. Remember to implement additional security measures, such as password hashing and preventing brute force attacks, to further protect your users’ data.
