What are the differences between hash functions and encryption when storing passwords in a PHP application?
When storing passwords in a PHP application, it is essential to use hash functions instead of encryption. Encryption is a reversible process, meaning that the original password can be decrypted if the encryption key is known. On the other hand, hash functions are designed to be irreversible, making them more secure for storing passwords. By using a secure hashing algorithm like bcrypt, passwords can be securely stored in a database.
// Hashing the password before storing it in the database
$password = 'user_password';
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
// Store $hashed_password in the database
