Stock 10.4 Server php error_reporting = ALL

Hello, I've searched high and low and cannot find the answer to this simple problem. Background: I have migrated from Linux to Mac OS 10.4 Server running the stock Apache/PHP/Mysql setup. I am virtual hosting a dozen web sites. The problem: I want to enable error_reporting for php. I have made the change in /private/etc/php.ini. I have restarted web services and even rebotted the server since this change. How do I get apache to read the php.ini file. Can I do it via command line.... and still utilize the Server Admin tool....? Thanks in Advance... Michael
