Working with Zend Server

To automatically configure a Zend Server :

The auto detection is triggered when Zend Studio is launched or when the Auto Detect Zend Server button is clicked.

For auto detection when Zend Studio is launched:

1. Ensure Zend Server is installed and running on the local machine.

2. Open Zend Studio.
   A popup balloon will appear in the bottom-right corner of the window indicating that a Zend Server installation has been detected and configured.

3. Click the icon to close the balloon or the 'click here' link to be taken to the Zend Server Integration help page.

To auto detect Zend Server after Zend Studio has been launched

You can manually trigger a Zend Server auto detection through the Servers view by performing the following steps:

1. Open the Servers view.
   This is available from the default PHP Perspective or can be manually opened by going to Window | Show View | Zend Servers | Servers.

2. Click the Auto Detect Zend Server icon on the toolbar.

3. If a Zend Server installation has been detected, a New Zend Server Found dialog is displayed asking whether you want to configure it to be the default server.

4. Click Yes to set it as the default server or No for the server to be configured by but not set as the default.

A Local Zend Server configuration is configured and added to your PHP Servers Preferences page.

To create a new PHP project on Zend Server ;

1. From the menu bar, go to File | New | PHP Project.
   The New PHP Project dialog is displayed.

2. Enter 'ZendServerProfiling' in the project name field.

3. Under the contents category, ensure the 'create project on a local server' option is selected.
   The directory path should point to the document root of your Zend Server.

4. Click Finish.
   The project will be created on your Zend Server's document root.

This procedure creates a purposeful performance issue in order to demonstrates how to profile an event:

1. Create a new PHP file in the project you created above by right-clicking the project in PHP Explorer view and selecting New | PHP File.

2. Name the file c-to-f_convert.php and click Finish.

3. Copy/paste the example code into the file. (Click here to see the code)
   (See the "Working with Zend Server" Tutorial in Zend Studio's Online Help for the example code.)

4. Save the file.

5. Run the application you created by right-clicking the c-to-f_convert.php file in PHP Explorer view and selecting Run As | PHP Web Page.
   The Run PHP Web Page dialog is displayed.

6. Ensure the URL in the Launch URL field points to the location of your file on Zend Server and click OK.
   The application is launched in Zend Studio's browser.

7. In the temperature field, enter '30' and click the Convert! button.
   Because the code used for this application contained a purposeful slowdown, this action should have been detected by Zend Server and saved as a performance event.

8. Open the Zend Server Event list by right-clicking your Zend Server configuration in the Servers view and selecting Show Server Event List.
   Or by clicking the arrow next to the Zend Server icon on the toolbar and selecting your Zend Server configuration from the drop-down list.
   If you have not yet configured your Zend Server password:

1.  A message will appear asking whether you want to configure this now.

2. Click Yes to be taken to the Zend Server preferences tab.

3. In the Authentication field, enter your Zend Server UI password and click Finish.

4. Reopen the Zend Server Event List as described in Step 8 above.

9. The Zend Server Event list is displayed.
   The last event displayed should be a Slow Request Execution (Absolute) Event created by our code slow down.

10. Click the event to see the event details.
    The event run time was higher than the one defined in the monitoring rules threshold.

Note:

To change this threshold, go to the Rule Management tab and click Edit for the Severe Slow Request Execution (Absolute) rule.

11. Click the Profile Event.
    A profiling session is launched in Zend Studio using the same parameters as were used during the slow request execution.

Note:

If no session is launched, see Setting Up Zend Server Integration to ensure you have correctly configured your integration settings in both Zend Studio and Zend Server .

12. Click Yes if asked to open the PHP Profile perspective.
    The Profiling views will display information regarding the request.

13. Explore the Profiling Execution Flow to detect the execution bottle-neck.
    You should see that the execution of ’r;myFunction ’r; took most of the time.

14. Double-click myFunction to view the code in the editor.

Now that the root-cause of the problem has been detected, you can debug or browse your code to diagnose and fix the error.

This procedure creates a purposeful PHP error event in order to demonstrates how to debug and diagnose the cause of the error:

1. In the same project as was created above, create a new PHP file by right-clicking the project in PHP Explorer view and selecting New | PHP File.

2. Name the c-to-f_convert2.php and click Finish.

3. Copy/paste the example code into the file. (Click here to see the code)
   (See the "Working with Zend Server" Tutorial in Zend Studio's Online Help for the example code.)

4. Save the file.

5. Run the application you created by right-clicking the c-to-f_convert2.php file in PHP Explorer view and selecting Run As | PHP Web Page.
   The Run PHP Web Page dialog is displayed.

6. Ensure the URL in the Launch URL field points to the location of your file on Zend Server and click OK.
   The application is launched in Zend Studio's browser.

7. In the temperature field, enter '30' and select the Fahrenheit to Celsius conversion type in the drop-down list.

8. Click the Convert! button.

9. Open the Zend Server Event list by right-clicking your Zend Server configuration in the Servers view and selecting Show Server Event List.
   -Or- by clicking the arrow next to the Zend Server icon on the toolbar and selecting your Zend Server configuration from the drop-down list.
   If you have not configured your Zend Server password:

1. A message will appear asking whether you want to configure this now.

2. Click Yes to be taken to the Zend Server preferences tab.

3. In the Authentication field, enter your Zend Server UI password and click Finish.

4. Reopen the Zend Server Event List as described in Step 9 above.

10. The Zend Server Event list is displayed.
    The last event displayed should be a PHP Error as a result of our PHP code error.

11. Click the event to see the event details.

12. Browse the Function Data and Request tabs to see the event details.

13. Click Debug Event.
    A debugging session is launched in Zend Studio using the same parameters as were used during the initial PHP error occurrence.

Note:

If no session is launched, see Setting Up Zend Server Integration to ensure you have correctly configured your integration settings in both Zend Studio and Zend Server .

14. Click Yes if asked to open the PHP Debug perspective.
    The debug views display information about your code.

15. Click the Resume button in the Debug view or click F8 to be taken to your problematic line of code.

16. Click the Step Over button in the Debug view or click F6.
    A Debug Warning message appears in the Console view detailing the error and its cause.

The code can now be easily fixed (in this case by replacing the "5 / 0" operation with "5 / 9").
