I swapped to old PHP 7.4 to update a WordPress project. I then could not switch back to 8.2+. I had the Laravel installer in the global composer dependency, which prevented running composer global update
Go to /Users/mike/.composer/ and temporarily remove the Laravel installer to be able to swap, then can probably put it back afterwards.
At the time of writing PHP 8.1 is the default, and I have 7.4 and 8.0 installed.
To swap them around link/unlink and then stop and start the appropriate Homebrew service.
Linking changes CLI version; starting the service affects the version Nginx connects to.
You may also want to change the binary that Tinkerwell loads.
The syntax to link unlink PHP 8.1 (default) are different to the other two. I would not have a clue why.
When you stop a PHP service, sometimes a “fallback” one automatically starts. It might not be the one you want, so you have to stop it and start the one you need.
brew unlink php && brew link phpbrew link --overwrite --force php@7.4
// or
brew link --overwrite --force php@8.0brew services list
brew services stop php@8.0
brew services start php
brew services start php@7.4 etc...Added PHP8.0 with Homebrew. I’m using the shivammathur/homebrew-php tap as recommended in Brent’s post.
nginx-restart //(custom alias I have set in .zshrc)
brew services restart php
brew services restart redisI think this will just be a matter of brew linking the desired version (if already installed), and restarting php/nginx.
brew link --overwrite --force php@8.0I’m not totally sure what the old 7.4 is called as far as Brew is concerned. It was the default back when I installed it, so maybe it’s just php , or possibly php@7.4
(A similar thing will probably happen now that PHP 8.1 is the default. I installed PHP 8.0 when it was, so it’s just php . Is it now php@8.0 ?)
Feb 2020 – replacing Apache with Nginx to fix broken dev env.
Nginx with PHP-FPM was giving 404 because the script name wasn’t being forwarded to PHP-FPM.
Needed this inside the fast_cgi file. It wasn’t there by default, but some random Googling turned it up 🙁
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;Nginx may start as non-sudo/root user and lack permission to bind to :80
In that case I brew services stop nginx, then sudo brew services start nginx.
MySQL died after rebooting after installing Qcachegrind.
I think the problem was brew update doing a ‘prune’ which removed /usr/local/etc/my.cnf.d
I recreated it manually and was able to start MySQL
cd /usr/local/bin
sudo mysql.server startbrew services restart php@7.2I was trying to change PHP settings, to be able to experiment with Xdebug profiling.
phpinfo() shows that it loads /usr/local/etc/php/7.1/php.ini , which is true, but didn’t seem the case because changes were not taking affect after restarting PHP and Apache.
I was restarting the wrong PHP with brew services restart php71. Even stopping it has no effect.
So that’s not the version that Apache is pointing to. It uses some other instance of the service that I don’t know how to restart without doing the whole computer!
sudo brew services restart php@7.1brew services list can also be useful, or even brew services list | grep php
