Function inop, but tosses no errors

[Twayne]

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).

I've sprinkled some echoes here and there to try to see what's running
but no help. I've indicated the ones that DO echo properly for me with
<-------.
I've checked syntax and pairing of brackets etc. in two differend
IDEs and all looks OK.
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!

Any Help?

Sorry for the omission.

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

>echo '<br/>$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

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;
guess I didn't hold my mouth right. Ya gotta love windows!

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.

OK.

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

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

$output = "Might be valid."; and
$output = "too short, " . strlen($email) . " characters.";

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_globals = 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
