Are there any best practices for managing SessionIDs in PHP forms to prevent encoding errors like "&"?

SessionIDs in PHP forms can sometimes be encoded incorrectly, leading to issues like "&" appearing in the SessionID. To prevent this, it's important to properly encode and decode the SessionID when passing it between pages. One way to do this is by using the base64_encode() function to encode the SessionID before storing it in the session, and then base64_decode() to decode it when retrieving it. 

// Encode the SessionID before storing it in the session
$encodedSessionID = base64_encode(session_id());
$_SESSION['encodedSessionID'] = $encodedSessionID;

// Decode the SessionID when retrieving it
$decodedSessionID = base64_decode($_SESSION['encodedSessionID']);
