How to Escape Strings for MySQL Queries Without Database Connectivity
In certain scenarios, you may require a function that mimics mysql_real_escape_string's behavior for dry testing purposes, without actually connecting to a database. This article explores the feasibility and limitations of this approach.
Can Strings Be Escaped Without a Database Connection?
Unfortunately, escaping strings securely without a database connection is not possible. Both mysql_real_escape_string() and prepared statements rely on a connection to the database to appropriately escape strings based on the current character set. Without this context, SQL injection attacks remain a threat.
Alternatives for Testing Purposes
If the purpose is solely testing, you can consider using mysql_escape_string() despite its deprecation. While it doesn't offer complete protection against SQL injection attacks, it is sufficient for testing purposes when you cannot connect to a database.
