What's the difference between __construct() and init()

I wa开发者_开发技巧s wondering what is the difference between __construct() and init() functions in a PHP application, more particularly in a Zend Framework application.

init() is called by the constructor.

init() isn't defined in the specification of PHP, it's only a method available with the Zend Framework to help initialize without having to rewrite the constructor yourself.

On the same topic :

__construct is a php magic method. It always exists and is called on object creation. init() is just a reguar method usually used in ZF..
