What's the difference? Is an IS_NULL > check slower? No, it's not slower, but it makes no sense to compare variable value to a type constant. Even if coincidentally constant value is the same one you need to compare to. -- Stanislav Malyshev, Zend Software Architect stas@zend.com http://www.zend.com/ (408)253-8829 MSN: stas@zend.com
