Running a PHP App with Tomcat: Step-by-Step Guide

While it might seem unconventional, it is indeed possible to run a PHP application using Tomcat. Here's a comprehensive guide to achieving this:

Requirements:

• Tomcat server
• PHP 5.2.5 or higher
• PECL 5.2.5 Win32 binaries

Instructions:

1. Install PHP: Download and install PHP to a specific directory, such as c:php-5.2.6-Win32.
2. Install PECL: Download and install PECL 5.2.5 binaries.

3. Configure PHP:

   • Rename php.ini-dist to php.ini under c:php-5.2.6-Win32.
   • Uncomment the line extension=php_java.dll in php.ini.

4. Copy Necessary Files:

   • Copy php5servlet.dll from PECL to c:php-5.2.6-Win32.
   • Copy php_java.dll from PECL to c:php-5.2.6-Win32ext.
   • Copy php_java.jar from PECL to tomcatlib.

5. Create PHP Directory:

   • Create a directory named "php" under tomcatwebapps.

6. Configure Servlet:

   • Copy phpsrvlt.jar from PECL to tomcatwebappsphpWEB-INFlib.
   • Unzip or unjar phpsrvlt.jar.
   • Modify netphpreflect.properties and netphpservlet.properties by setting library=php5servlet.
   • Recreate the jar file using jar cvf php5srvlt.jar net/php/*.

7. Create Web.xml:

   • Create a web.xml file in tomcatwebappsphpWEB-INF with the following content:

     <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>

8. Update System Path:

   • Add the PHP path (c:php-5.2.6-Win32) to your Windows environment variables.

9. Test:

   • Create a sample PHP file (test.php) under tomcatwebappsphp.
   • Restart Tomcat.
   • Navigate to localhost:8080/php/test.php to verify that the PHP app is running.
