Why is it important to hash passwords before storing them in a database, and how can password hashing be implemented in PHP?

It is important to hash passwords before storing them in a database to protect user data in case of a security breach. Hashing converts the password into a fixed-length string of characters that cannot be reversed, making it more secure than storing plaintext passwords. In PHP, password hashing can be implemented using the password_hash() function to securely hash passwords before storing them in a database. 

// Hashing a password before storing it in a database
$password = "secret_password";
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

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