Is /usr/local/opt/php54/bin/php alright compared to /usr/local/bin/php?

Is /usr/local/opt/php54/bin/php alright compared to /usr/local/bin/php?

I'm just a starter with these things, so I want to know if having my php
in the first directory fine. It got installed there using homebrew, but I
think it should be installed in the second directory.
/usr/local/opt/php54/bin/php
shows up when I type type in "which php."
I use Mac OS X 10.8. Whenever I type in "php" in the Terminal, it goes to
PHP but it just ends there. Just a blank thing.
