Seriously. I’m doing too much php stuff!
Here are a few things I learned in the last couple of days:
apt-get install php5-mcrypt
dpkg -l php5-mcrypt
ii php5-mcrypt 5.4.6-0ubuntu6 amd64 MCrypt module for php5
php -m | grep -c mcrypt
php -m | grep mcrypt
And to install xhgui+xhprof, follow this tutorial (README is lacking)
