What are common mistakes to avoid when implementing password protection in PHP scripts?

One common mistake to avoid when implementing password protection in PHP scripts is storing passwords in plain text. Instead, passwords should be securely hashed before being stored in the database. Another mistake is using weak hashing algorithms, such as MD5 or SHA1. It is recommended to use stronger algorithms like bcrypt or Argon2 for password hashing. 

// Incorrect way of storing password in plain text
$password = $_POST['password'];
// Save $password in the database

// Correct way of securely hashing the password before storing it
$password = $_POST['password'];
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
// Save $hashed_password in the database
