Created A Mess Trying to Change OSX PHP Version

So, in a bit of a mess here. I was TRYING to change the version of my El Capitan PHP version (5.6.2) to PHP7, however I made a bit of a mess.

Now I just want to send things back to normal.

When I run which php, I get this:

/usr/local/php7/bin/php

which should be default:
/usr/bin/php

When I run php -v, I get this error:

dyld: Library not loaded: /usr/local/php5/lib/libtidy-0.99.0.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found
Trace/BPT trap: 5

I did quite a few things, wrongly. Starting with wrong paths. This started the mess (STUPID):

 sudo mv /usr/local/bin/php /usr/local/bin/php7
 sudo ln -s /usr/local/php7/bin/php /usr/local/bin/php

How can I get thing back to their default state?
