Couple simple php questions

[robmorin]

Hello all, just wanted to verify a few things with respect to php on an Omega system..

1- When i installed it i said to choose php5, does this mean php5 is the default? I mean any php scripts that run run as php5?

2- How wold one run a php script as php4?

3- When i need to modify the php file i should do it in the domains /var/www/fcg/domain.com/php5/php.ini file since php5 is the default?

4- I should never really touch the /etc/php5/ and /etc/php4 dirs unless it somethign system wide?

Thanks to all in advance..

Rob..
