thank you, stuart.

in the interest of wrapping up the archive of this thread on topic, may i

in a statement like:


if $something is not set, i.e. isset($something) would, in the same context,
evaluate to false, the statement WILL NOT trigger an error at any level or
throw an exception.

the reason i ask is this: sometimes it's important to unset a variable at a
position in a script where as programmer i don't know if the variable is set
or not. session variables are good examples. i sure don't what reports of
such unsets in my php error logs. but i also don't want to do:

    if (isset($something)) unset($something);

if i don't need to.

and the answer is: i don't.
