when making changes to php.ini i have two questions.

1. i went into /etc/php.ini and edited the text. the only lines that are
actually necessary to edit DO NOT have ";" at the start, correct? reason
i ask is because the line "allow_call_time_pass_reference = On" appears
in 2 places but only once without a ";" in front of it. 

2. for the changes regarding memory, do i need the text in the second
set of parentheses as well:

> memory_limit = 32M      ; Maximum amount of memory a script may
> consume (8MB) (8MB barfs on FC3/PG8)
