What alternative methods can be used in PHP to pass session IDs without relying on cookies, especially in situations where browser settings may block them?

When browser settings block cookies, session IDs can be passed in URLs or through hidden form fields. This can be achieved by appending the session ID to URLs or including it as a hidden input in forms. However, passing session IDs in URLs can expose them to potential security risks, so it's important to encrypt or hash the IDs before passing them. 

// Passing session ID through URL
session_start();
$sessionId = session_id();
$url = "http://example.com/page.php?sid=" . $sessionId;
header("Location: $url");
exit;

// Passing session ID through hidden form field
session_start();
$sessionId = session_id();
echo "<form action='process.php' method='post'>";
echo "<input type='hidden' name='sid' value='$sessionId'>";
echo "<input type='submit' value='Submit'>";
echo "</form>";
