Mac M1/Arm Chip doesn't seem to work

[nerdylist]

Hello,
I keep getting this error:

Fatal error: Uncaught Error: Call to undefined function ray() in /Users/****/Sites/ray/index.php:6 Stack trace: #0 /Users/****/.composer/vendor/laravel/valet/server.php(234): require() #1 {main} thrown in /Users/****/Sites/ray/index.php on line 5

<?php $stuff = "whatever"; echo "Hello World"; echo $stuff; ray($stuff);

After following the setup instructions and installing globally.

I'm on a Mac Mini M1/Arm Chip.

I've gone through changing PHP versions, updating Composer etc... Can't seem to get it to work. Any ideas?
