How can PHP developers securely store and manage passwords for admin logins?

To securely store and manage passwords for admin logins in PHP, developers should use a strong hashing algorithm like bcrypt to hash the passwords before storing them in the database. This helps protect the passwords from being easily compromised in case of a data breach. Additionally, developers should never store passwords in plain text or use weak hashing algorithms like MD5 or SHA1. 

// Hashing the password using bcrypt
$password = 'admin123';
$hashedPassword = password_hash($password, PASSWORD_BCRYPT);

// Storing the hashed password in the database
// Example SQL query: INSERT INTO users (username, password) VALUES ('admin', '$hashedPassword');

// Verifying the password during login
$enteredPassword = 'admin123';
if (password_verify($enteredPassword, $hashedPassword)) {
    // Password is correct
    // Proceed with the login process
} else {
    // Password is incorrect
    // Display an error message
}
