Replace the numbers with data extraction queries: http://example.com/page.php?id=-1 UNION SELECT 1, database(), user(), 4-- - .
If the id parameter references a file path, an attacker might try: index.php?id=../../../../etc/passwd inurl php id 1

Google Dorking, also known as Google Hacking, uses advanced search operators to find information not easily available through standard searches. These operators instruct Google to look for specific text strings within website code, URLs, or file structures.
The attacker clicks a result. If the page looks like a standard article or product, they append a single quote ( ' ) to the URL: https://site.com/page.php?id=1' Share public link $id = $_GET['id']; $result =
As a developer, treat every $_GET['id'] with suspicion. As a security enthusiast, use this dork responsibly—to patch systems, not plunder them. And as a user, remember that the seemingly random string inurl php id 1 represents the constant, invisible war between convenience and security that defines the modern web.
When a website is vulnerable through its php?id parameter, the consequences can be devastating for both the business and its users.
The database knows the id is data, not code. A malicious 1 OR 1=1 becomes a harmless string.
$id = (int)$_GET['id']; // Forces the input to be an integer, neutralizing SQL strings Use code with caution. Use Robots.txt and Noindex Tags
