What is the proper way to retrieve and handle a hidden SID in a form for data insertion in PHP?

When retrieving a hidden SID in a form for data insertion in PHP, you can use the `session_id()` function to retrieve the session ID. It is important to sanitize and validate the SID before using it in your database query to prevent any security vulnerabilities. You can then insert the retrieved SID along with other form data into your database. 

// Retrieve the hidden SID from the form
$hidden_sid = $_POST['hidden_sid'];

// Sanitize and validate the SID
$clean_sid = filter_var($hidden_sid, FILTER_SANITIZE_STRING);

// Get the session ID
$session_id = session_id();

// Insert the session ID and other form data into the database
$query = "INSERT INTO your_table_name (session_id, other_column) VALUES ('$session_id', 'other_data')";
// Execute the query
