Why check the return of mysql_real_escape_string()?

No, I don't think you're being paranoid. (or we're both paranoid).

In a sense you are missing something as it's no longer recommended to use the mysql_ family of functions. Instead use mysqli or PDO. Both of these provide parameterised queries which will automatically escape your input data for you.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
