[ale] [OT] need help with 2php SOLUTION

[George Carless]

I'm really not sure what you're referring to, here.. there's no reason to
re-query a database for data if you already know what the data has been
set to.  Perhaps posting some actual (rather than psuedo) code would help
explicate the situation?

I didn't quite understand Brian's example, either (and I do this stuff for
a living) .. Brian, did you mean something like:

if (myfunction($param)) {
	echo "Sendemail";
}


?  Or am I missing something?  Your example
wouldn't seem to parse, from where I'm sitting.  But the general notion of
checking for the return value is a sound one.

Cheers,
--George
