Step 6: Troubleshoot your Application

To troubleshoot your application:

1. Open the Event Details page for the same PHP Error event from Step 5:
   1. In the Zend Server Ui, go to the Overview | Events page.
   2. In the Filters area, click Show Filters.
   3. In the Event Type category, select the PHP Error filter.
   4. From the list of filtered events, click event ID 9.

2. The Backtrace tab displays the exact line in the code triggering the error (line 350 in the 'mtrig.php' file).
3. To help you quickly diagnose the error and find the root cause, you can debug the event using the integration with Zend Studio.
   In the Zend Studio Diagnostics area at the bottom of the page, click .
   Zend Server initiates a debug session for the event URL in Zend Studio.

   Important:

   These action items are only available if Zend Studio is installed on your machine, and Zend Server is configured to communicate with it. For more information, see Integrating with Zend Studio.

4. In the Zend Server UI, go the Overview | Code Tracing page.
