What are potential pitfalls of using ID numbers to differentiate between different types of data in a PHP project?

Using ID numbers to differentiate between different types of data in a PHP project can lead to potential conflicts if the same ID is used for different types of data. To avoid this issue, it's better to use a separate identifier for each type of data, such as a prefix or a separate column in the database. 

// Example of using a prefix to differentiate between different types of data
$type = 'user';
$id = 123;

$userData = getUserData($type, $id);

function getUserData($type, $id) {
    // Query the database using the type and ID to retrieve the user data
    // Return the user data
}
