 ## Programming Paradigms
 
-PHP is a flexible, dynamic language that supports a variety of programming techniques. It has evolved dramatically over the years, notably adding a solid object-oriented model in PHP 5.0 (2004), anonymous functions and namespaces in PHP 5.3 (2009), and traits in PHP 5.4 (2012).

 ### Functional Programming
 
+PHP has had annonymous functions since PHP 5.3:
+
+{% highlight php %}
+<?php
+$greet = function($name)
+{
+    print("Hello {$name}");
+};
+
+$greet('World');
+{% endhighlight %}

 ### Meta Programming
 
+Ruby developers often say that PHP is lacking `method_missing`, but it is available as `__call()`. There are many Magic Methods available 
+like `__get()`, `__set()`, `__clone()`, `__toString()`, etc.
