Please rate this bug important so that it gets fixed http://bugs.php.net/bug.php?id=31098

warning! 5.0.1 - 5.0.3 "breaks" EMPTY() function

On: PHP Vulnerabilities Announced

Watch out when upgrading!

<?
$a = 'foobar';
print empty($a->nothere) ? 'empty' : 'not empty';
?>

This code prints 'empty' with 5.0.1, but 'not empty' with 5.0.3.

You must check all your code for the use of empty() with a string!

I wish PHP would warn everyone about this sort of thing.

Here is the man page...nothing said about it: http://www.php.net/empty
