In this article, we will learn how to display logged-in user information using PHP and its various inbuild methods.

When building a web application that requires authentication, it is often necessary to display the logged-in user's information on various pages. This could be useful in applications such as e-commerce websites, banking websites, and more. We can implement this with the help of PHP and its functions.

Let?s understand this with the help of some examples.

Example 1

In this example, we will create a login/logout system wherein the user will get authenticated once he is logged in, and will get redirected to the dashboard page with his information visible. The user can then logout from the dashboard to reset the session.

Filename: login.php

Filename: logout.php

Filename: dashboard.php

   


   
Your username is: 
   
Logout

Example 2

In this example, we will display the logged-in user's information on the profile page. The user needs to be authenticated to access the profile page.

Filename: login.php

Filename: logout.php

Filename: profile.php

 'John Doe',
      'email' => 'john.doe@example.com',
      'phone' => '1234567890',
   );
?>


   


   
Welcome, 

   
Profile Information
   
Name: 
   
Email: 
   
Phone:

Conclusion

In this article, we learned how to display the user information of a logged-in user in PHP. By following the simple steps outlined above, we easily retrieved and displayed user information on any page of our web application. This allowed us to provide a personalized experience for each user and make our application more user-friendly.
