How to install php 5.6 with homebrew if from this year it is EOL?

I just used shivammathur/homebrew-php without any problems.

brew tap shivammathur/php
brew install shivammathur/php/php@5.6

The repository is on Github: https://github.com/shivammathur/homebrew-php

(the exolnet/homebrew-deprecated mentioned in other answers doesn't seem to work anymore)

brew tap exolnet/homebrew-deprecated

brew install php@5.6

I tried exolnet/homebrew-deprecated but it have some problem with xdebug & pecl. So I recommend you use official one.

Ref this because of long post:
