I want to upgrade to PHP 8 with Homebrew on Mac (macOS Big Sur Version: 11.2) But there is a problem!
1- Show my version of PHP:
TERMINAL:
MyUser@MacBook-Pro ~ % php -v
WARNING: PHP is not recommended
PHP is included in macOS for compatibility with legacy software.
Future versions of macOS will not include PHP.
PHP 7.3.24-(to be removed in future macOS) (cli) (built: Dec 21 2020 21:33:25) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.24, Copyright (c) 1998-2018 Zend Technologies
2- Install version 8 of PHP:
MyUser@MacBook-Pro ~ % brew install shivammathur/php/php@8.0
Warning: shivammathur/php/php 8.0.2 is already installed, it's just not linked.
To link this version, run:
brew link php
3- Brew Link PHP:
MyUser@MacBook-Pro ~ % brew link --overwrite --force php@8.0
Error: Formulae found in multiple taps:
* shivammathur/php/php@5.6
* exolnet/deprecated/php@5.6
Please use the fully-qualified name (e.g. shivammathur/php/php@5.6) to refer to the formula.
How to solve this problem?
