Laravel Valet 3 Released With Multi-Version PHP Support

The Laravel team released the next major version of Laravel Valet (3.0), which introduces running multiple versions of PHP in Valet applications side-by-side.

This super exciting new feature is now officially released, as a part of Valet 3!

To update:
1. Update your global Valet constraint to "^3.0"
2. Run `composer global update laravel/valet`
3. Run `valet install`
4. Party On, Wayne!https://t.co/nBH6rds7ha https://t.co/PvtLKHzx96

Previously, you could specify which version of PHP Valet used to serve applications locally using valet use php@7.2, but now you can do so on a per-site (including a default) basis using the following commands:

cd path/to/app
 
# Isolate the current project
valet isolate php@7.4
 
# Isolate a site by name
# This command will also install the PHP version
# if it's not already installed.
valet isolate php@8.0 --site=laravel9x

After isolating a site, you can see that my local Valet install is serving projects using various isolated PHP versions:

And another application using the default installed version of PHP (v8.1):

Another challenge you might run into with this setup is running commands on the CLI with the matching PHP version. What I do is create a symlink to the brew version of PHP somewhere in my path:

ln -s $(brew --prefix php@7.4)/bin/php $HOME/bin/php74
 
php74 --version
PHP 7.4.28 (cli) (built: Mar  3 2022 06:26:49) ( NTS )
...

Using this version of PHP, you can prefix commands to composer, etc.:

php74 $(which composer) install

You might also need to symlink other binaries like pecl in the same way to install extensions.

PHP Monitor

Off the heels of PHP Monitor 5.0 for macOS, the author released PHP Monitor 5.2 with support for Valet 3, making management of isolated PHP versions a breeze:

🚀 PHP Monitor 5.2 is now available!

Most notable: this release adds support for Valet 3. With this new version of Valet, you can now easily set a version of PHP *per domain*! 😎
