What are some common best practices for inserting data into a database using PHP forms?

When inserting data into a database using PHP forms, it is important to sanitize user input to prevent SQL injection attacks. One common best practice is to use prepared statements to securely insert data into the database. Additionally, validating user input before inserting it can help ensure data integrity. 

// Assuming you have already established a database connection

// Sanitize user input
$name = mysqli_real_escape_string($conn, $_POST['name']);
$email = mysqli_real_escape_string($conn, $_POST['email']);

// Prepare and execute the SQL statement using prepared statements
$stmt = $conn->prepare("INSERT INTO users (name, email) VALUES (?, ?)");
$stmt->bind_param("ss", $name, $email);
$stmt->execute();

// Close the statement and connection
$stmt->close();
$conn->close();
