    What has changed in PHP 5.0.x

    PHP 5 and the integrated Zend Engine 2 have greatly
    improved PHP’s performance and capabilities, but great care has
    been taken to break as little existing code as possible. So
    migrating your code from PHP 4 to 5 should be very easy. Most
    existing PHP 4 code should be ready to run without changes, but you
    should still know about the few differences and take care to test your code
    before switching versions in production environments.
