The comma can also concatenate string!
You may want to run the following lines:
<?php
$a = 3;
$b = 5;
echo $a, "abc", $b;
?>

Erm, I wasn't being a smart ass was I? Certainly didn't mean to be. I
was aiming for some light humoured banter as is the style on this list.
Sometimes I miss that target, and sometimes my comments are just soooo
witty and clever than no-one gets them ;)
Incidentally, despite your bold claims that I'm at fault, you are
actually wrong.
The comma here is simply separating the arguments passed to echo (which
isn't really a function, more a language construct as it does not need
the parenthesis required by a normal function call).
Your output will all appear (and thus it seems like concatenation) but
there is no actual concatenation going on. You are simply passing in
multiple arguments, all of which are output in order.

someone else has made a mistake but it actually backfires and blows up
in their face)
