How to Escape Strings Without Connecting to MySQL?

In certain scenarios, the need arises to escape strings without establishing a database connection. While mysql_real_escape_string() is the ideal solution, it requires a connection to the database.

However, due to concerns regarding SQL injection attacks, the use of mysql_escape_string() is discouraged. This article explores the challenges and presents an alternative approach to safely escape strings.

Impossibility of Safe Escaping Without Database Connection

Attempting to escape strings without a database connection compromises string safety. Both mysql_real_escape_string() and prepared statements rely on a connection to accurately escape strings based on the appropriate character set. Without such, SQL injection attacks remain feasible using multi-byte characters.

Testing Alternative for Dry Runs

For testing purposes, mysql_escape_string() can be employed as a viable alternative. While it may not guarantee absolute prevention of SQL injection attacks, it is impossible to create a safer solution without an active database connection.
