Hello,
I have a quick question: To use a custom solution for inhibiting sql injection attacks and not a database specific solution like mysql_real_escape_string()
http://php.net/manual/en/function.mysql-real-escape-string.php
... that will run on any database, not just MySql, would the following be a viable solution:
a. addslashes() to all variables and
b. remove specific unwanted characters from input including:
-- [comment sign in SQL]
' [single quote]
It is possible to just destroy the unwanted characters in a login form and prohibit use of those characters in username and password fields.
Would a. plus b. above provide reasonably good protection to inhibit sql injection attacks, or what is the best database independent approach using php and not a database function?
Thank you for any help.
Robin.
