What best practices should be followed when binding form data to SQL parameters in PHP?

When binding form data to SQL parameters in PHP, it is important to use prepared statements to prevent SQL injection attacks. This involves using placeholders in the SQL query and binding the form data to these placeholders. Additionally, it is recommended to validate and sanitize the form data before binding it to the SQL parameters to ensure data integrity. 

// Assuming $conn is the database connection object and $form_data is an array containing the form data

$stmt = $conn->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $form_data['value1'], $form_data['value2']);
$stmt->execute();
$stmt->close();
