How Can I Safely Escape Strings for Dry Testing Without a Database Connection?

Escaping Strings Without Database Connectivity

Question:

How can I escape strings accurately without establishing a database connection? I need this functionality for dry testing purposes to avoid SQL injection vulnerabilities.

Answer:

Regrettably, it is not feasible to escape strings safely without connecting to a database. Both mysql_real_escape_string() and prepared statements rely on a database connection to tailor the escaping mechanism to the specific character set of the target database. Neglecting this connection exposes your application to SQL injection attacks, particularly those involving multi-byte characters.

Testing Considerations:

If your primary objective is testing, you could resort to mysql_escape_string(). While not foolproof against SQL injection attacks, it remains a viable option due to the lack of more secure alternatives without a database connection. However, it is strongly advised against using mysql_escape_string() in production environments.
