PHP Install on Mac OS X 10.5.7

Hi,

I'm following the guide to install PHP on my Mac.

My Mac's build is:

Mac OS X 10.5.7
2.4Ghz Intel Core 2 Duo
2 GB 1067 MHz DDR3

So anyway... i'm following the PHP install guild for Mac OSX and it starts by saying:

Locate and open the Apache configuration file. By default, the
location is as follows: /etc/httpd/httpd.conf

so i open up Terminal enter sudo, type "cd /" on the command line and find "etc"

BUT there doesn't seem to be a httpd folder there??

instead, i ran:

bash-3.2# find / -name httpd.conf -type f -print
find: /dev/fd/3: Not a directory
find: /dev/fd/4: Not a directory
/Library/Application Support/Apple/ParentalControls/ContentFiltering/httpd.conf
find: /net/localhost: Operation timed out
find: /net/broadcasthost: Operation timed out
/private/etc/apache2/httpd.conf
/private/etc/apache2/original/httpd.conf

i'm guessing the files in question are:

/private/etc/apache2/httpd.conf
/private/etc/apache2/original/httpd.conf

But i'm not sure which one i need to configure?

Thanks,

Stephen
