MAMP PRO Uninstalled – How to Remove Terminal Commands

Source:
To "uninstall" MAMP, you only have to delete the MAMP directory and
everything returns to the original state

I uninstalled MAMP using the Uninstaller from Applications/MAMP PRO. I checked all checkboxes to restore everything. Surprisingly after that, typing mysql -p or php -v still works:

I saw that another MAMP directory exists in Applications. When I removed (still stays in the Trash just in case) it I got:

slick-mac:~ slick$ php -v
-bash: /Applications/MAMP/bin/php/php5.6.2/bin/php: No such file or directory
slick-mac:~ slick$ mysql -p
-bash: /Applications/MAMP/Library/bin/mysql: No such file or directory

and that almost does the trick but finally how to remove all those references. I would like to completely remove those commands (php, mysql, etc.)

Am I missing some symlinks?

EDIT:

I've found this for php in /usr/bin

slick-mac:bin slick$ ls -alh | grep php
-rwxr-xr-x     1 root   wheel    10M 18 Oct 09:47 php
-rwxr-xr-x     1 root   wheel   3.2K  9 Sep 17:30 php-config
-rwxr-xr-x     1 root   wheel   4.4K 23 Aug 11:22 phpize
slick-mac:bin slick$ pwd
/usr/bin

should I remove those 3 items?
