Function inop, but tosses no errors

PS Re: Function inop, but tosses no errors

PS Target: PHP 5.2.2 on remote server, using 5.2.5 locally on winXP Pro.
Sorry for the omission.

HI,

Below is fully functional, non-functional code :^): In other words,
it works, but it doesn't do anything and darned if I can see why. None
of the 3 $email assignments result in any output. I just kept
two commented out so I could easily switch addresses for testing,
thus the "#"s. It does not kick out any errors and syntax checks
valid with tswebeditor (freebie).

But, I've obviously pulled something stupid somwehere. It's pretty
simple code and I think it's evident what's going on so I haven't yet
added many comments. Basically, check the length left and right, how
many DOTs and @, and no dots where they shouldn't be.
But none of the if's result in any output & don't seem to be getting
run, indicating something pretty obvious I'm sure, just not obvious to
me!

Maybe a stupid question, but do you actually call this function
somewhere?

>echo ' $output is ' . $output; # <--- $OUTPUT DOES NOT ECHO

This line should cause an E_NOTICE error, since $output is not defined
anywhere.

Aww, darn it, yes; I forgot to inlcude the code. It's just a
validateEmail($ email) statement after the "--...---" at the bottom of my
posted code.

Nope; and I do have errors turned on, including notices, in .ini.

$output is assigned multiple times as the function runs. e.g.
$output = "Might be valid."; and
$output = "too short, " . strlen($email) . " characters.";
.... etc.
Or did you mean something else I'm not catching on to?
Each if(...){...} has a " $output = "...

I thought possibly $email wasn't getting picked up or it was a scope
problem, but I don't see anything. Time for me to sleep on it again, I
think.

Thanks, Micha

Did a Restart; now it's working! Damn! I already tried that once;

Just for clarity: The function functions; I didn't mean it has no other
problems<g>. Just in case a newbie decides to try it out; didn't want
to leave a false impression.

Yes, inside the function. But the line I mentioned was _outside_ the
function. But it's probably in the part you didn't post. ;)

Problem seems to be solved, but a last question: Did you change anything
in the PHP configuration? Such changes may require a restart of the web
server, but not a restart of the whole system. That's a bit strange.

OH, I see it. No, It was misplaced; I'd done a lot of rearranging and
screwed up replacing it properly.

Hmm, I don't think so, but ; not exactly sure when I did it or if it
could count as a config change though: I did add a php.ini to my php
directory with only a "register_globa ls = off " line in it. AFAIK I
don't need it; don't even recall why I used it now, I'll have to check
my notes again. I did not change any config files though (ini, cfg,
etc).
However, restarting the server first should probably have been my
first effort, not the Restart; I'll have to remember that just for GPs.

Thanks again,

Twayne
