For future reference, just about any function that uses is at the
beginning should return a boolean result. So if (is_array()) can also be
checked with if (!is_array())
This should apply to all the php included
Yeah as soon as I saw this example, I figured that was the case for
example something like
if (!empty())
and so on.

If you use ISSET together with a hidden field when posting a form to itself
to enter a second-state, is there a way of using it again to get to a
third-state.

first I check to see if it's been submitted and then using ELSE I

I'm new to PHP, so how would I go about using sessions?
I assume one needs to update _SESSION['name'] = $name; with the state of

Then I'm stuck again!

This will return false positives for cases where the variable has not
been set to null but HAS been set to the empty string or to a 0? This
isn't really the same as the OP requested. However, isset() also returns
false for

The following script is from Kevin Yank's book (Sitepoint).
When I test it _without_ entering a name in the text box and hit submit, the
_next_ page

If I replace
!isset()
with

Ok, here's the deal. I like to use $_GET and $_POST variables without values
to notify my scripts that some action must be taken. For example, given the

input type=hidden name=edit
My blah.php script
