4.3.3-RC1 => possible bug in in_array()?

-----BEGIN PGP SIGNED MESSAGE-----

Hi.

I've just found weird thing about in_array() function.

Platform: FreeBSD 5.1/PHP 4.3.3-RC1

Consider this code:

$this->_array_a and $this->_array_b ARE IDENTICAL

$data = array();
foreach ($this->_array_a as $key => $value) {
if (! in_array($key, $this->_array_b)
$data['added'][$key] = $this->_array_a[$key];
}

Therefore after execution $data should be empty.

But there is whole $this->_array_a in $data after execution...

The following code works ($data is empty after execution):
foreach ($this->_array_a as $key => $value) {
if (! isset($this->_array_b[$key]))
$data['added'][$key] = $this->_array_a[$key];
}

Why is this happening?
