What is the significance of using PASSWORD_DEFAULT over PASSWORD_BCRYPT in PHP for password hashing?

Using PASSWORD_DEFAULT over PASSWORD_BCRYPT in PHP for password hashing is recommended because PASSWORD_DEFAULT will automatically use the best available algorithm for hashing passwords, which is currently bcrypt. This allows for future algorithm upgrades without needing to change the code. It ensures that your application is using the most secure hashing algorithm available. 

// Hashing a password using PASSWORD_DEFAULT
$password = 'secret_password';
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
