It will not make much sense to deliver this extension for non-ZTS PHP. non-ZTS PHP is used with Apache in pre-fork model and here this extension will not be used. For this configuration, using memcache extension (which is already integrated) within OpenSolaris will be the appropriate way to store session informations. >> 2.6 Packaging and Delivery >> >> PHP ZTS enabled runtime and configuration files will delivered >> within SUNWphp52u and SUNWphp52r respectively.

This extension is part of PHP base bundle and is necessary to work with Sun Web Server . This project compiles this NSAPI plugin and its dependent extensions and delivers them along with base php package. b) This project also delivers a 'configure script' to get this PHP NSAPI extension loaded within Sun Web Server. Hope this clarifies. - Sriram
