How to Password Protect a Web Page Using PHP

Protecting web pages with passwords is essential in preventing unauthorized access to sensitive information or private content. In PHP, you can easily implement password protection using basic authentication.

To password protect a web page using PHP, follow these steps:

1. Create a new PHP file for the protected web page, for example, protected-page.php.
2. Include the following PHP code at the top of the file to prompt users for a username and password:
<?php
$username = 'admin';
$password = 'password';
if (!isset($_SERVER['PHP_AUTH_USER']) || $_SERVER['PHP_AUTH_USER'] != $username || $_SERVER['PHP_AUTH_PW'] != $password) {
header('WWW-Authenticate: Basic realm="Restricted area"');
header('HTTP/1.0 401 Unauthorized');
echo 'Access denied';
exit;
}

3. Update the $username and $password variables with your desired credentials.
4. Save the file and upload it to your web server.
5. When users access the protected page, they will be prompted to enter the specified username and password.
6. Upon successful authentication, the user will be granted access to the protected content.

Implementing password protection in PHP is a simple yet effective way to secure your web pages. Remember to use strong and unique passwords to enhance security.
