Laravel：传递变量以查看和访问它作为函数中的全局变量

Question

I'm trying to pass a variable to a view so that I can have it as a global variable in a function, but it's not working. I'm not getting any output from the function, but I'm also not getting an error message. Where am I going wrong?

web.php

<?php
  Route::get('/', function() {
    $abc = 'abc';
    return view('front')->with(['abc'=>$abc]);
  });
?>

front.blade.php

<?php
  function fn() {
    global $abc;
    return $abc;
  }
?>

{{ fn() }}

You can just straight up use your variable, without declaring it global:

@php
  function fn() {
    return $abc;
  }
@endphp

{{ fn() }}
