Installing Pear, what did I do by entering these commands on my terminal - unix

Question

I'm trying to figure out how to install Pear on my Mac (10.6.6).
Not understanding what they're telling me at pear.php.net, I got some code from http://clickontyler.com/blog/2008/01/how-to-install-pear-in-mac-os-x-leopard/
First, I entered curl http://pear.php.net/go-pear > go-pear.php in my terminal.
It resulted in this output
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 88004 100 88004 0 0 47537 0 0:00:01 0:00:01 --:--:-- 59744
What does that all mean? Am I on the right track?
Next, I entered sudo php -q go-pear.php
and it gave me the long output below. In short I have no idea where I am in the installation process. However, I'm pretty sure that I'm not where I'm supposed to be at following the tutorial at http://clickontyler.com/blog/2008/01/how-to-install-pear-in-mac-os-x-leopard/
because the tutorial tells me to select all the default choices, and I don't see any options to select.
The next line of code is asking me to modify the php.ini files and it requires a password so I'm worried about doing it...Can anyone tell me if I'm on the right track?

Answer 1

php does not have an argument -q. Its also mentioned in go-pear.php (http://pear.php.net/go-pear) itself, but I dont know, what it wants to tell me. However, try
sudo php go-pear.php
and then follow the instructions.
Update:
-q was used, to start the interpreter in "quiet" mode. It seems, that this option does not exists anymore, because php always starts "quiet", but it should not cause an error, anyway. Now make sure you are in the same directory as the file go-pear.php before you call php go-pear.php.

Answer 2

The first part shows that you successfully downloaded the file to go-pear.php.
The second part is showing that -q isn't a valid option. The third part is asking for the root password, since you're doing 'sudo'.
I used this, though I wasn't installing on Mac:
