Strongly-typed views with PHP

UserProfile.php

<?php

/**
 * Example: strongly typed view with PHP.
 *
 * Rather than traditional "flat views", why not put your views
 * in a dedicated namespace and declare them as classes?
 *
 * Some advantages:
 *
 * - IDE support (autocomplete, use of type-hints)
 * - Better performance when rendering many times during same request
 * - Reflection support (enables meta-programming techniques)
 * - Provides a location for dedicated helper-methods for complex view-specific logic
