disable_functions not working in httpd.conf

Hey All, Was just trying the following and disable_functions is not working? Although safe mode and open_basedir are! What is really strange that when phpinfo is called the disable_functions value is phpinfo, can't seem to disable echo either, I don't want to put these in php.ini as I still want to be able to have a fully fledged php running from the main document root. <VirtualHost *> ServerAdmin foo@bar.com.au DocumentRoot /home/test/public_html ServerName test.foo.bar.com.au ErrorLog logs/test.foo.bar.com.au-error_log CustomLog logs/test.foo.bar.com.au-access_log common <Directory /home/test/public_html> AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps php_admin_value open_basedir /home/test/public_html php_admin_value user_dir /home/test/public_html php_admin_value disable_functions phpinfo php_admin_flag safe_mode On php_admin_value safe_mode_allowed_env_vars PHP_ php_admin_value safe_mode_protected_env_vars LD_LIBRARY_PATH php_admin_value sendmail_from test@foo.bar.com.au </Directory> </VirtualHost> What am I doing wrong, any suggestions welcome on the above conf too :) Thanks in advance, Joseph
