I'm a noob to Linux and running apache2/php5/MySQL on it. I'm running Linux Mint 13. Anyway, someone above mentioned that the first posts were in 2003! I must say, thank you LinuxQuestions.Org for not deleting this post because even though today is 01Sep2012-Saturday, I still found the information posted from 9 years ago highly useful! Thank you! Now, with reference to installing the PECL whachamacallit's, I found the php.ini file by using: locate php.ini, and then I used nano /path/to/php.ini to edit it.
