What are the best practices for creating a registration script in PHP?

When creating a registration script in PHP, it is important to follow best practices to ensure the security and functionality of the registration process. This includes validating user input, hashing passwords for storage, and handling errors gracefully. By implementing these practices, you can create a secure and user-friendly registration system. 

<?php
// Validate user input
$username = $_POST['username'];
$email = $_POST['email'];
$password = $_POST['password'];

if(empty($username) || empty($email) || empty($password)) {
    echo "Please fill in all fields";
    exit;
}

// Hash password for storage
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Insert user data into database
// Add your database connection code here

// Handle errors gracefully
if($query) {
    echo "Registration successful";
} else {
    echo "Registration failed";
}
?>
