This article will talk about the failure of brew link to change the php version. I hope it will be helpful to friends in need!
Problem description:
I installed three php versions through brew
php 5.6 php 7.4 php 8.0
$ php -v
PHP 8.0.3 (cli) (built: Mar 4 2021 20:45:17) ( NTS ) Copyright (c) The PHP Group Zend Engine v4.0.3, Copyright (c) Zend Technologies with Zend OPcache v8.0.3, Copyright (c), by Zend Technologies
Disable 8.0 and use 7.4
$ brew unlink php@8.0 && brew link php@7.4 Unlinking /usr/local/Cellar/php/8.0.3... 0 symlinks removed. Linking /usr/local/Cellar/php@7.4/7.4.16... 264 symlinks created. $ php -v
It’s still the same version
It’s the same when I opened a new terminal 8.0.3
PHP 8.0.3 (cli) (built: Mar 4 2021 20:45:17) ( NTS ) Copyright (c) The PHP Group Zend Engine v4.0.3, Copyright (c) Zend Technologies with Zend OPcache v8.0.3, Copyright (c), by Zend Technologies
The operation is quite satisfactory
Where is the setting?
Analysis and solution:
You can try to install a PHP selector
brew update brew upgrade
Reference documentation
https://github.com/shivammathur/homebrew-php
Install the specified php brew install shivammathur/php/php@7.3
Link php version brew link --overwrite --force php@7.3
If an error occurs
Warning: Already linked: <Cellar Path> To relink: brew unlink <formula> && brew link <formula>
Execute
brew unlink php@7.3 brew link --overwrite --force php@7.3
RestartService
apache brew services restart httpd nginx brew services restart nginx
Installation Result
To enable PHP in Apache add the following to httpd.conf and restart Apache: LoadModule php7_module /usr/local/opt/php@7.0/lib/httpd/modules/libphp7.so <FilesMatch \.php$> SetHandler application/x-httpd-php </FilesMatch> Finally, check DirectoryIndex includes index.php DirectoryIndex index.php index.html The php.ini and php-fpm.ini file can be found in: /usr/local/etc/php/7.0/ php@7.0 is keg-only, which means it was not symlinked into /usr/local, because this is an alternate version of another formula. If you need to have php@7.0 first in your PATH run: echo 'export PATH="/usr/local/opt/php@7.0/bin:$PATH"' >> ~/.zshrc echo 'export PATH="/usr/local/opt/php@7.0/sbin:$PATH"' >> ~/.zshrc For compilers to find php@7.0 you may need to set: export LDFLAGS="-L/usr/local/opt/php@7.0/lib" export CPPFLAGS="-I/usr/local/opt/php@7.0/include" To have launchd start shivammathur/php/php@7.0 now and restart at login: brew services start shivammathur/php/php@7.0 Or, if you don't want/need a background service you can just run: php-fpm
