I’ve been hearing from people confused about Zend Server editions on IBM i. Yes, Community Edition was removed with Zend Server 7/8, but Zend replaced that with the no-charge “Basic” edition. The Basic edition exists only on IBM i. It requires registration but at no cost. Zend Server for IBM i can be downloaded here.
While I often recommend the Professional or Enterprise editions of Zend Server for the value-added tools and for Zend’s professional support, rest assured that free PHP still exists, with the Basic edition.
For more information, here is the current list of Zend Server editions for IBM i.
[Update: See PHP 7 and Free Basic Zend Server Edition for IBM i ]
