Re: Re: Found a bug in 4.2.3 re: <TD> and echo vs. <?php?>

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(); Daevid Vincent wrote:

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?

How does a parsing error like this go un-noticed for so long? Obviously I took out all the interesting stuff in the page

be blamed.
