I'm wondering if this can be done, and if so, what's the proper way to do
it.
For the current issue I'm trying to unset some variables with common names
and I would like to step through them with a loop. Here's where I'm at to
give you an idea but the code doesn't work.
for ($i = 2; $i <= 4; $i++) {
unset($level$iName);
unset($level$iUrl);
}
so the code unsets
unset($level2Name);
unset($level2Url);
unset($level3Name);
unset($level3Url);
unset($level4Name);
unset($level4Url);
I guess I could create a variable before the unset like so
$unsetA = "level" . $i . "Name";
but that seems cloogey.
Thanks,
Tom
