Good Day!!!

In this article, we are going to learn on How To Create User Login Logout Session Timeout Using PHP. This user login is a very common tutorial for us. In this case, we are going to add a function. In the user login, we set a session expiration time when the user logged-in. If the account of user elapsed to the set time then the user will no longer access his/her account and it will automatically log out after refreshing the page. HTML Source Code This HTML source code is to show the login form for the user. 
  1. <form method="post" action="">
  2. <?php if($message!="") { ?>
  3. <div id="message" class="blink_text"><?php echo $message; ?></div>
  4. <?php } ?>
  5. <table border="0" cellpadding="10" cellspacing="1" class="tblLogin">
  6. <tr class="tableheader">
  7. <td align="center" colspan="2">Login Details</td>
  8. </tr>
  9. <tr class="tablerow">
  10. <td align="right">Username</td>
  11. <td><input type="text" autofocus="autofocus" class="textbox_detail" name="user_name"></td>
  12. </tr>
  13. <tr class="tablerow">
  14. <td align="right">Password</td>
  15. <td><input type="password" autofocus="autofocus" class="textbox_detail" name="password"></td>
  16. </tr>
  17. <tr class="tableheader">
  18. <td align="center" colspan="2"><input type="submit" class="btn_submit" name="submit" value="Login"></td>
  19. </tr>
  20. </table>
  21. </form>
PHP Script This PHP script is used to check the session account of the user if the login session expiration time is reached. 
  1. <?php
  2. session_start();
  3. include("functions.php");
  4. $message="";
  5. if(count($_POST)>0) {
  6. 	if( $_POST["user_name"] == "admin" and $_POST["password"] == "admin") {
  7. 		$_SESSION["user_id"] = 1001;
  8. 		$_SESSION["user_name"] = $_POST["user_name"];
  9. 		$_SESSION['loggedin_time'] = time();  
  10. 	} else {
  11. 		$message = "Invalid Username or Password!";
  12. 	}
  13. }
  14.  
  15. if(isset($_SESSION["user_id"])) {
  16. 	if(!isLoginSessionExpired()) {
  17. 		header("Location:home.php");
  18. 	} else {
  19. 		header("Location:logout.php?session_expired=1");
  20. 	}
  21. }
  22.  
  23. if(isset($_GET["session_expired"])) {
  24. 	$message = "Session is Expired. Please Login Again.";
  25. }
  26. ?>
Our tutorial look like this: This is the login form. Login Form This is our Home Page. Home Page If the user session is a timeout. Time Out So what can you say about this work? Share your thoughts in the comment section below or email me at [email protected]. Practice Coding. Thank you very much.
