I\'m running PHP with MAMP on OSX 10.5.8
So if I want to run a script from console I always need to write
/applications/mamp/bin/php5.3/bin/php path/
Create a file called .bash_profile on your home directory (if you don't have this file already), and add this to the file:
.bash_profile
export PATH=/Applications/mamp/bin/php5.3/bin:$PATH
Then quit and relaunch Terminal.app
