Instructions for setting up Tomcat 6 and PHP 5 as a portable  distribution:

What you need:
-   Tomcat 6, zip distribution (http://tomcat.apache.org/)
    -   I used 6.0.18  (apache-tomcat-6.0.18.zip)
-   PHP 5, zip distribution
    -   I used 5.2.9-1  (php-5.2.9-1-Win32.zip)
-   PECL
    -   The latest time as of this writing is 5.2.6.  However, this 
        version does not include the necessary servlet extensions, so 
        you will need 5.2.5.  (pecl-5.2.5-Win32.zip)
-   Java
    -   I used the 1.6.0u12 JDK.  I think a normal JRE will also work.


1.  Choose a directory to keep everything in.  I used C:\tomcat_php\.  I wil 
    refer to this as BASE_DIR
2.  Unzip the Tomcat distribution to BASE_DIR.  Rename the apache-tomcat-6.x
    directory to tomcat6
3.  Unzip PHP to BASE_DIR\php5
4.  Install the JDK.  Copy C:\Program Files\Java\jdk1.6.0_xx to BASE_DIR.  
    Rename it to jdk1.6.0
    
    
At this point, you should have a directory structure which looks roughly 
like this:

    C:\
    |   tomcat_php\
    |   |   jdk1.6.0\
    |   |   php5\
    |   |   tomcat6\
    
5.  In BASE_DIR\php5, copy php.ini-dist to php.ini
6.  Edit php.ini.  Find the Dynamic Extensions section and add 
    extension=php_java.dll at the bottom of it
7.  Extract php5servlet.dll from the PECL zip to BASE_DIR\php5.  Rename it to 
    php5srvlt.dll
8.  Extract php_java.dll from the PECL zip to BASE_DIR\php5\ext
9.  Create a directory named phptest in BASE_DIR\tomcat6\webapps.
9.  Extract phpsrvlt.jar from the PECL zip to phptest\WEB-INF\lib (using the 
    phptest directory you just created)
10. Create web.xml in phptest\WEB-INF with the following contents:

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance "
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    <servlet>
        <servlet-name>php</servlet-name>
        <servlet-class>net.php.servlet</servlet-class>
    </servlet>
    <servlet>
        <servlet-name>php-formatter</servlet-name>
        <servlet-class>net.php.formatter</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>php</servlet-name>
        <url-pattern>*.php</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>php-formatter</servlet-name>
        <url-pattern>*.phps</url-pattern>
    </servlet-mapping>
</web-app>


11. Create index.php in phptest with the following contents:

<?php phpinfo(); ?>


12. Create startup.bat in BASE_DIR with the following contents:

@echo off
setlocal

for %%x in (%0) do set BatchPath=%%~dpx
for %%x in (%0) do set BatchDrive=%%~dx
cd /d %BatchPath%

set PATH=%BatchPath%php5;%PATH%
set JAVA_HOME=%BatchPath%jdk1.6.0

cd tomcat6\bin
startup.bat


13.  Create shutdown.bat in BASE_DIR with the following contents:

@@echo off
setlocal

for %%x in (%0) do set BatchPath=%%~dpx
for %%x in (%0) do set BatchDrive=%%~dx
cd /d %BatchPath%

set PATH=%BatchPath%php5;%PATH%
set JAVA_HOME=%BatchPath%jdk1.6.0

cd tomcat6\bin
shutdown.bat


14. Everything should now be set up.  Use startup.bat and shutdown.bat to start 
    and stop Tomcat.  With Tomcat started, you should be able to visit
    http://localhost:8080/phptest/index.php
    in a web browser and get a PHP info page.
