A product ID is a unique identifier (typically a numeric primary key) assigned to an item in the store's database. ocni.unap.edu.pe Dynamic Loading : When a user clicks a product, the browser sends a request (e.g., product.php?id=1 Database Query : The PHP script grabs the ID from the URL using $_GET['id'] and queries the database: SELECT * FROM products WHERE id = 1 Common Pattern : You will often see variations like shop.php?id=1&a=add refers to an like "add to cart". Stack Overflow 2. The Security Risk (SQL Injection) $row['name']
The "PHP ID 1 shopping" anti-pattern persists because developers conflate authentication with authorization. Exposing raw database IDs in URLs is not inherently insecure, but doing so is a critical vulnerability. Modern PHP e-commerce systems must implement object-level access controls, use indirect references where beneficial, and routinely test for IDOR. As online shopping grows, so does the incentive for attackers to simply change id=1 to id=2 — a low-effort, high-reward exploit that no production system should allow.
