Can you provide a more realistic example?
Just don't code anything after the last line of code that contains the
exit? Surely.
http://uk.php.net/manual/en/function.eval.php does say that ...
"A return statement will immediately terminate the evaluation of the string ."
So, there's your answer I suppose.
Replace "exit" with "return".
