Migrating from php4 to php5

[andrewshim]

My web host will be migrating from php 4 to 5 and they have issued notice to upgrade my code. I think I'm fine but there is one issue I don't quite understand :

An object with no properties is no longer considered "empty".

What does this mean exactly? I have the following script that is important to my site :

if (empty($stringID)) {
header("Location: http://www.example.com/page.php");
exit();
}

This tests to see if the URL that the visitor entered has a required variable. If it doesn't it diverts to another page. How does php5 handle this?

as long as the old setup had register_globals off, that seems to me one of the biggest issues.

in your example above, barring the register_globals setting, it would behave exactly the same
