+Zend engine
+===========
+
+The Zend engine is a set of components that make PHP what it is. The most important Zend engine component is the 
+*Zend Virtual Machine*, which is composed of the *Zend Compiler* and the *Zend Executor* components. We could also add 
+the OPCache zend extension in such category. Those three components are the heart of PHP (or the brain, you choose), 
+they are critical and they are the most complex parts of all the PHP source code. In the current chapter, we'll try to 
+open them and detail them.
