What is a potential pitfall of passing item IDs through the URL in PHP, as seen in the example provided in the forum thread?

Passing item IDs through the URL in PHP can expose sensitive information and make it easier for malicious users to manipulate the data. It is recommended to use a more secure method, such as using POST requests or encrypting the IDs before passing them in the URL. This can help prevent unauthorized access and protect the integrity of the data. 

// Example of encrypting the item ID before passing it through the URL
$item_id = 123;
$encrypted_id = base64_encode($item_id);

// In the URL
<a href="view_item.php?id=<?php echo $encrypted_id; ?>">View Item</a>

// In the receiving page
$decrypted_id = base64_decode($_GET['id']);
// Use $decrypted_id in your code
