I may be crazy, but wouldn't if ($variable) work just as well? If the
string is empty it'll return a negatory on that check.
Lemme double check that.
$testVar = ;
if ($testVar) {
echo Yes;
}
else {
echo No;
}
Yeah, ok. That ran just fine under 4.2.3.

RE: [PHP] newbie's question
Err... sorry. The logic was there but my fingers got a bit ahead of my
brain. The check works, but if you want to just check if it's empty turn
the conditional to a negative, like so:
if (!$testVar) {
etc.
}
That makes it If NOT $testVar

RE: [PHP] Newbie's question about \n
If you check the source of your code you'll see that in source the text is in two lines. \n doesn't work as br, so this is about how HTML works, not plain text.
