The perhaps most controversial change in behavior has happened to the
behavior of the empty(). A String containing
only the character '0' (zero) is now considered empty while it
wasn't in PHP 3.
This new behavior makes sense in web applications, with all input
fields returning strings even if numeric input is requested, and
with PHP's capabilities of automatic type conversion. But on the
other hand it might break your code in a rather subtle way,
leading to misbehavior that is hard to track down if you do not
know about what to look for.
