Execute function in Laravel after response sent to client

routes.php

<?php


Route::get('/', function () {

    $response = Response::json([
        'process' => true
    ]);

    return Response::withShutdownTask($response, function () {
        file_put_contents(public_path('__task__.txt'), 'teste');
    });

});

Response::macro('withShutdownTask', function ($response, callable $callback) {

    $response->header('Connection', 'Close');
    $response->header('Content-Encoding', 'none');
    $response->header('Content-Length', mb_strlen($response->getContent()));

    register_shutdown_function(static function () use ($callback) {
        ignore_user_abort(true);
        flush();
        @ob_end_flush();
        sleep(3);
        $callback();
    });

    ob_start();

    return $response;
    
});
