I downloaded the PHP5 tarball from http://www.entropy.ch/software/macosx/php/ and did the install.
Before the install, I commented out all the php4 lines in my apache config file(
The entropy package installed under
/usr/local/php5and it added a new config file (
/private/etc/httpd/users/+entropy-php.conf), which is included by the main apache httpd.conf file...restart apache, that's it!
