php_ directives

Hi Some assistance with this would be appreciated. I'm obviously missing something stupid. My old PHP3 directives in the httpd.conf file don't work anymore. For example, for each VirtualHost I used to be able to use "php3_engine off" and "php3_safe_mode on", etc. These lines now cause a problem during httpd startup. I've tried php_* php4_* without success. Any pointers? The error message during httpd startup is: Invalid command 'php4_safe_mode', perhaps mis-spelled or defined by a module not included in the server configuration. PHP4 is compiled as a module and included with the LoadModule line in conf/httpd.conf. PHP4 appears to be working fine otherwise though (ie, if I comment out the offending lines). Thanks Henry
