Commands in the Mac terminal

I tried to install Composer on OSX 10.10.3 following the site instructions: 

curl -sS https://getcomposer.org/installer | php

And after that I am no longer able to execute the commands curl, ls, among others. The terminal does not execute these commands and returns me the following message: 

-bash: curl: command not found

How can I fix this?

Or
