I've recently been informed that we have a little more budget left so we're trying to spend it on stuff to make things better here. I've been asked to look at info and pricing for Zend Optimizer, the Zend Load Balancer and some other Zend stuff.
Is there anything else you can think of I should have them consider for a PHP shop? This could be tools or software or something. It doesn't have to be 100% PHP focused, but it should be useful with PHP or with website design and programming (ala Photoshop, but we have that already).
Thank you much.
