What are common errors encountered when trying to integrate a password script in PHP websites?

One common error when integrating a password script in PHP websites is not properly hashing the passwords before storing them in the database. This can lead to security vulnerabilities as plain text passwords are easily accessible. To solve this, always use a secure hashing algorithm like bcrypt to hash passwords before storing them in the database.

// Hash the password before storing it in the database
$password = 'password123';
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Store $hashed_password in the database
