Subject: Re: [PHP-DEV] Adding/Updating ZVal Arrays to Object
From: mrice@rcs.us ("Matthew C. Rice")

Marcus,


     Thanks a bunch! I had a similar style pdf I found on the pecl site 
titled 200510_zend_conf_php_extension_development.pdf , but it was 
lacking a little on OOP. This looks like exactly what I needed. Between 
this and the Sara Golemon book I hope to fill a major gap.. Thanks again !!!
