Are there any general improvement suggestions for PHP scripts, such as avoiding storing passwords in plaintext?

One common improvement suggestion for PHP scripts is to avoid storing passwords in plaintext. Instead, passwords should be securely hashed before storing them in a database. This helps to protect user data in case of a security breach. 

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

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