What do I need to escape in an Insert ?

Suppose I'm going to insert the content of a <TEXTAREA> in a table.
Obviously, there will be characters that could potentially confuse the SQL
statement. What (and how) do I need to escape the data to make it acceptable for
an Insert ?

I currently use the PHP's addlashed function, is it enought ?

Thanks for your response !

Bye!
