Use a view composer to invoke a function in Blade.

Here’s an interesting use of  a view composer that’s useful for invoking functions in blade. Create and register a service provider…
php artisan make:provider Composer

In its boot() method…

public function boot()

for all blade instances…

view()->composer('*', function ($view) {

declare a function…

$view->with('briefTime', function ($x)
return strrev(substr(strrev($x), 3));
}); }); }

This example defines a way to quickly remove seconds from SQL datetime.

to support the following blade syntax…

<div class="pr-5">{{$briefTime($survey['started_at'])}}</div>
