RE: [PHP] if statment
I'm pretty sure that if it was in a form but left blank isset() won't work
because it is set in the globals, it is just empty. I've never used
empty(), so I cannot comment on its behavior.

Re: [PHP] if statment
below is what I have currently
?php if ($HTTP_GET_VARS[id] == ) { ?
its empty
?php }?
Now when I change the == to I receive the following error:
Notice: Undefined index: id in c:\inetpub\wwwroot\_\users.php on line 103
Why would that not work - In asp it does, but I can't get it workin in php.
If that doesn't make sense, I would like to have an if statement the says,
if HTTP_GET_VARS[id] is NOT empty then show something else
Thanks for you guy's help and time

RE: [PHP] if statment
Because not equal is !=, not
I think I posted a link to the documentation a few eamils ago in this
thread. Check it out, these are all really easy syntax questions, so you'll
save yourself much hair pulling by just reading the section on basic syntax.

Are you kidding? You do realize that ASP and PHP are not the same thing, right?
If that doesn't make sense, I would like to have an if statement the says,
if HTTP_GET_VARS[id] is NOT empty then show something else
if (!empty($_GET['id']))
{
echo 'Something else';
}

Re: [PHP] if statment
You should be using if(!isset($HTTP_GET_VARS['id'])){ Otherwise, it
generates an eror when it simply doesn't exist. and nothing (an
unset variable) are NOT the same.
