Str is working without import facade in laravel 8

I am using str class in my helpers like below without import facade it is working fine without throwing any error. I am feeling little strange how it is working can any one explain.

if(!function_exists('testHelper')){
    function testHelper($string){
        $numbers = Str::replace(['(',')','-',' '],'',$string);
        return $numbers;
    }
}

if no need to import facade explicitly for str class ,how come it is working in which file it is bootstraped.Thanks in advnace !!

Solution

  • Laravel's Facade and some classes are registered as an alias.
    It can be used without importing only in the global scope.
    Blade view, config file, custom helpers, etc.

    // blade
{{ Str::replace() }}

    // controller
use Illuminate\Support\Str;
Str::replace();

// or (not recommended)
\Str::replace();
