Neither works. You're doing something like this in your other code:

function foo(){
 echo "foo";
}
echo foo();

The foo() doesn't return the (non-existant) value from echo, it simply echo()s and returns nothing, and there's nothing wrong with echo()ing nothing. It would fail if you were using

function foo(){
 return echo "foo";
}
echo foo();

Mmm. I'm still not following and not completely convinced.
Changing "echo alarmLightYMD();" to simply "alarmLightYMD();" in the bottom
function doesn't print anything in the table cell at all (for the first test
case).
While your idea at first makes sense and does seem like a newbie mistake
(and you are correct, I do have nested "echo" statements come to think of
it). What I don't get is why it's not consistent. "Expanding" the relevant
lines, it should be like this:
echo "<TD>".(echo "<IMG SRC='images/light_red.gif'>")."</TD>";

Which fails, and the other line would be (which works):

<TD><?php echo (echo "<IMG SRC='images/light_red.gif'>"); ?></TD>
In my book, they're both double echoing the output if you will... Are you
with me on that?
So again, why does the second one work and the first one doesn't?

It's a coding error... at least I think so.

change alarmLightMySQL just return the results not "echo" them... echoing them doesn't make much sense inside another echo statement...

Here, try this bullshit...

I can't upgrade to a more recent version as I'm not in

control of the

server, but I've tried it with both 4.1.2 and 4.2.3 on

linux with a RH

install. Can anyone confirm or dispute this bug exists in

later versions?

How does a parsing error like this go un-noticed for so long?

Obviously I took out all the interesting stuff in the page

and so that can't
be blamed. This is about as bare skeleton test case as you can get.

*sigh*
