Assuming you have a Google App Engine website running with Java enabled and also localy installed the GAE Java SDK and the Google Eclipse plugin.

Assuming also that you did the Java Getting Started tutorial to get hands-on experience with the GAE Java SDK and the Google Eclipse Plugin.

Then you can also get PHP running on GAE with below steps.

1) Create a Google Web Application inside Eclipse

Optional: De-select GWT on the "New Web Application project" wizzard.

2) Copy resin.jar from Resin 4.0 to WEB-INF/lib

Add resin.jar to the java build path: Right-click on the project-name, select 'properties' then 'Java build path' and the add resin.jar under 'Libraries'

3) Modify war/WEB-INF/web.xml so that it contains (also) below content

<welcome-file-list>
 <welcome-file>index.php</welcome-file>
</welcome-file-list>

<servlet>
 <servlet-name>quercus</servlet-name>
 <servlet-class>com.caucho.quercus.servlet.GoogleQuercusServlet<servlet-class>
</servlet>

<servlet-mapping>
 <url-pattern>*.php</url-pattern>
 <servlet-name>quercus</servlet-name>
</servlet-mapping>

4) Add below lines to war/WEB-INF/appengine-web.xml

<static-files>
 <exclude path="/**.php" />
</static-files>

<resource-files>
 <include path="/**.php" />
</resource-files>

5) Create the war/index.php file.

<?php 

 phpinfo();

?>

6) Run the development server.

7) Surf to: http://localhost:8080/
