$php-v

PHP 8.0.3 (cli) (built: Mar 4 2021 20:45:17) (NTS) Copyright (c) The PHP GroupZend Engine v4.0.3, Copyright (c) Zend Technologies with Zend OPcache v8.0.3, Copyright (c), by Zend Technologies

Deactivate 8.0 to use 7.4

$brew unlink php@8.0 & & brew link php@7.4Unlinking / usr/local/Cellar/php/8.0.3... 0 symlinks removed.Linking / usr/local/Cellar/php@7.4/7.4.16... 264 symlinks created.$ php-v

Still the same version.

It's the same with my new client 8.0.3.

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 SetHandler application/x-httpd-php Finally, check DirectoryIndex includes index.php DirectoryIndex index.php index.htmlThe 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" > > ~ / .zshrcFor 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@7.0Or If you don't want/need a background service you can just run: php-fpm, thank you for your reading.
