- Now we are going to move leopard’s php to a safe place…

sudo mv /usr/bin/php /usr/bin/php-old

sudo ln -s /Applications/MAMP/bin/php5/bin/php /usr/bin/php

- If you have PEAR already installed, we are going to move it as well. If you don’t have PEAR, this will obviously error out which you can ignore.

sudo mv /usr/bin/pear /usr/bin/pear-old

- Link MAMP’s PEAR into bin…

sudo ln -s /Applications/MAMP/bin/php5/bin/pear /usr/bin/pear

pear channel-discover pear.symfony-project.com
pear install symfony/symfony

- Now place link symfony into bin…

sudo ln -s /Applications/MAMP/bin/php5/bin/symfony /usr/bin/symfony
