My Validation Base Class

I was asked how I deal with validation / create and update validation rulesets. Well here is one method I have used. Don't be afraid to build on top of what the framework has already given you. In my projects I use a base class for almost anything. You never know when you want your classes to inherit some common functionality. My BaseValidator actually has some pretty useful methods and properties in it.

<?php

namespace FooProject\Internal\Validators;

use FooProject\Internal\Sanitizers\BaseSanitizer;

@foreach(array_chunk($posts, 3) as $postSet)
   <div class="row"> <!-- this div will surround every three posts -->
        @foreach($postSet as $post)
            <h3>{{ $post['title'] }}</h3>
        @endforeach
    </div>
@endforeach

Why objects (usually) use less memory than arrays in PHP

This is just a small post in response to [this tweet][tweet] by Julien Pauli (who by the way is the release manager for PHP 5.5). In the tweet he claims that objects use more memory than arrays in PHP. Even though it can be like that, it's not true in most cases. (Note: This only applies to PHP 5.4 or newer.)

The reason why it's easy to assume that objects are larger than arrays is because objects can be seen as an array of properties and a bit of additional information (like the class it belongs to). And as array + additional info > array it obviously follows that objects are larger. The thing is that in most cases PHP can optimize the array part of it away. So how does that work?

The key here is that objects usually have a predefined set of keys, whereas arrays don't:
