lately it has been very irritating for me because I almost have a fully functioning site about to be launched. This may not seem like a problem, however my web host is running an old version of PHP so I cannot use MySqli_* or PDO, so I am stuck with the deprecated version (MySql_). A user here on S.O has told me that it is IMPOSSIBLE to prevent sql injection attacks whilst running MySql_.
Question: Is it impossible to secure my website from sql injection whilst using MySql_*?
