How do I upgrade PHP in Mac OS X?

Question

I feel this is an awfully obtuse question to ask, but strangely, this problem is poorly documented.

I would like to upgrade PHP, but there are several problems:

Answer 1

I think one simple way to do it, is:

1 - Check you where is your current PHP:

$ which php
$ /usr/local/bin/php

You see? Usually, our commands that we run is a link in /usr/local/bin so...

2 - Unlink this current link of PHP

unlink /usr/local/bin/php

If you prefere, before unlink it, check the path and then remove php files (do ls -al /usr/local/bin | grep php and then rm -rf into desired path)

3 - Install PHP 7.1

curl -s http://php-osx.liip.ch/install.sh | bash -s 7.1

4 - Create new link (using php 7.1 bin that you have installed)

ln /usr/local/php5-7.1.9-20170914-100859/bin/php /usr/local/bin/php

Like I said, its a simple way I think.
