Im tring to rewrite some code to use single/double quotes correctly (as
correct as can be).

If I use
$result=mysql_query('SELECT book FROM ' . TAB_AUTHORS . " WHERE aid =
$aid");
I get an mysql error.  That should be correct, if I understand it right.

But if I use
$result=mysql_query('SELECT book FROM ' . TAB_AUTHORS . " WHERE aid =
'$aid'");
it works.


So what I need to know is that do I have to ride the fine thin line for
correctness and speed???
