- Use aliases for the ultimate DX
While Rocketeers app will allow you to use different PHP versions on your webservers, it previously was very difficult to use different PHP versions on your local machine using Laravel Valet.
Since june 2022 Laravel Valet got a very nice upgrade in using different PHP versions and easily switch between them when working concurrently on different projects.
Isolate a PHP version per project
The first command that's new is
valet isolate this command can be used to isolate a project using one specific PHP version. After that the Nginx server that Valet installs on your Mac knows which PHP version to use for your project.
For example the command for a project locked into using only PHP 8.1 is:
valet isolate firstname.lastname@example.org
Use the specific PHP version even in your command line
Valet provides the ease of use to map local folders to hostnames in the browser and run them locally in the browser, using the correct PHP version. When using PHP from the command line, it is also possible to automatically let your Terminal know which PHP version to use when you run commands from the base path of your project.
For this specific use case Valet offers an
valet php command. This command aliases the PHP version within the folder of your project to the isolated PHP version.
Use aliases for the ultimate DX
To further optimize the DX you can make yourself even more comfortable. Include this alias in your
~/.bashrc and you can keep using
php to execute commands using the correct PHP version in your CLI:
alias php="valet php"
In order to run also Composer on the same PHP version, set also an alias up with absolute path to Composer to keep using it like
composer require ...:
alias composer="php /usr/local/bin/composer"
