$array = [
    'user'= > ['username'= >'something'].'app'= > ['creator'= > ['name'= >'someone'].'created'= >'today']].$dot_array = array_dot($array);

tap()

It takes two arguments: a value and a closure. The value will be passed to the closure, and the value will be returned. The closure return value is irrelevant. 

$user = App\User::find(1);

return tap($user.function($user) {
    $user->update([
        'name'= >'Random']); }); /** * it does not return a Boolean value, but the User Model. If you don't have a transitive closure, you can use any method of the User Model. * The return value will always be the value regardless of the actual method returned. In the following example, it will return the User Model instead of a Boolean value. * The update method returns a Boolean value, but because tap is used, it returns the User Model. * /$user = App\User::find(1);

return tap($user)->update([
    'name'= >'SomeName'
]);Copy the code
