What potential pitfalls should be considered when dealing with multiple IDs that have been saved in PHP?

When dealing with multiple IDs saved in PHP, potential pitfalls to consider include ensuring that the IDs are properly sanitized to prevent SQL injection attacks, maintaining data integrity by checking for duplicates or incorrect IDs, and handling errors gracefully to prevent any unexpected behavior. 

// Example of sanitizing multiple IDs saved in PHP
$ids = $_POST['ids']; // Assuming IDs are passed through a form
$clean_ids = array_map('intval', $ids); // Sanitize IDs by converting them to integers
