What are the best practices for handling user authentication and access control in PHP when sharing links with passwords?

When sharing links with passwords in PHP, it is important to securely handle user authentication and access control to prevent unauthorized access to sensitive information. One way to achieve this is by using strong password hashing techniques and implementing proper access control checks before granting access to the requested resource. 

<?php

// Check if the password is correct before granting access
if ($_POST['password'] === 'your_password_here') {
    // Password is correct, allow access to the resource
    echo "Access granted!";
} else {
    // Password is incorrect, deny access
    echo "Access denied!";
}

?>
