In the context of PHP development, how can developers effectively track and manage thread IDs to maintain consistency and prevent errors in data retrieval and display?

To effectively track and manage thread IDs in PHP development, developers can use session variables to store and retrieve the thread ID throughout the user's session. By storing the thread ID in a session variable, developers can ensure consistency in data retrieval and display, preventing errors that may occur if the thread ID is not properly managed.

// Start or resume the session
session_start();

// Set the thread ID in a session variable
$_SESSION['thread_id'] = 123;

// Retrieve the thread ID from the session variable
$thread_id = $_SESSION['thread_id'];

// Use the thread ID in data retrieval and display
echo "Thread ID: " . $thread_id;
