The Zend Debugger is a remote debugging tool for developers working
with Zend Studio.
The Zend Debugger is an API that communicates with the Zend (PHP) Engine
to retrieve runtime information and reveal it in Zend Studio for debugging
purposes.
Note: If your machine has multiple IP addresses, make sure you define all
IPs as allowed hosts in Zend Server.
