What are the consequences of losing admin access in a PHP forum and how can it be resolved?

Losing admin access in a PHP forum can result in the inability to manage users, content, and settings, leading to potential security risks and a lack of control over the forum. To resolve this issue, you can create a script that allows you to reset the admin password or promote another user to admin status.

// Reset admin password in PHP forum
include 'config.php';

$new_password = 'new_admin_password';
$hashed_password = password_hash($new_password, PASSWORD_DEFAULT);

$query = "UPDATE users SET password = '$hashed_password' WHERE username = 'admin'";
$result = mysqli_query($connection, $query);

if($result) {
    echo "Admin password reset successfully.";
} else {
    echo "Error resetting admin password.";
}
