[PHP] Re: Creating Session Variables

[nooper]

If you dont have register globals on, but find it convenient to access
$varname instead of $_SESSION['varname'],
you can extract($_SESSION), thought that has potential for other name
conflicts and confusion, so be careful if you use extract();

[PHP] timestamp from uniqid()

[nooper]

Would there be a way to extract a timestamp from uniqid(), since the
function is based on the microsecond, and its purpose is not to be random in
anyway, simply unique. I understand that it is not supposed to act as a
timestamp, just wondering if anyone has a method of extracting a date or
time from a uniqid.
Thanks,
nooper
