Debugger

The Zend Debugger component enables remote debugging of PHP scripts with Zend Studio.

The Zend Debugger communicates with the Zend (PHP) Engine to retrieve runtime information and present it in Zend Studio for root cause analysis purposes.

Note:

If your machine has multiple IP addresses, make sure you define all the IPs as allowed hosts in Zend Server.

The Zend Debugger API communicates with the Zend (PHP) engine to reveal PHP runtime information such as variables, call stack and environment information. This information is then displayed and set up in Zend Studio to enable server side debugging, profiling and code coverage.
