Changing php directives inside apache config file

Hi all. I'm trying to alter the include_path for three different sites running on the same machine, and I do not want to use ini_set in each file. Here's what I've set up for each virtual host inside my httpd.conf file: <VirtualHost ###.###.##.###> <IfModule mod_php4.c> php_value include_path ".:/usr/local/lib/php:/path/to/cmsdev.unbc.ca/html" </IfModule> ServerAdmin cms@unbc.ca DocumentRoot /path/to/cmsdev.unbc.ca/html ServerName cmsdev.unbc.ca ErrorLog /path/to/cmsdev.unbc.ca/logs/cmsdev.unbc.ca-error_log CustomLog logs/dummy-host.example.com-access_log common ErrorDocument 403 /403.php ErrorDocument 404 /404.php </VirtualHost> However even after restarting apache the include_path is not being set correctly. Can anyone give me any advice as to where I'm going wrong? Cheers and TIA, Pablo
