Best way to escape strings for sql inserts?

What is the best way to escape strings for sql inserts, updates?

I want to allow special characters including ' and ". Is the best way to search and replace each string before I use it in an insert statement?

Thanks

You should be using parameterized queries (so by extension, a DB interface library that supports parameterized queries) so that SQL injection can't happen.

If you're talking about data values for your fields, then the best way is to use mysql_real_escape_string(). (Some people like mysqli; can't say I do.) If you're talking about allowing user-submitted queries... well, let's hope you're not talking about that.
