How can PHP developers ensure the security of admin logins in their applications?

To ensure the security of admin logins in PHP applications, developers should implement strong password hashing techniques, use prepared statements to prevent SQL injection attacks, and implement measures such as rate limiting and account lockouts to prevent brute force attacks. 

// Sample PHP code snippet for securing admin logins

// Hash the password before storing it in the database
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Use prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username);
$stmt->execute();

// Implement rate limiting and account lockouts
// Check if the number of failed login attempts exceeds a certain threshold
if ($failed_login_attempts >= 5) {
    // Lock the account and notify the user
}
