Using PHP With Tomcat

PHP version 5 is not currently supported as it does not include the necessary servlet code.

Prerequisites

Patch for PHP configure Script

Prior to version 2.4 of Servlet Specification, the name of the servlet jar file was servlet.jar. In version 2.4 of the Servlet Specification, this name was changed to servlet-api.jar. Tomcat 4 uses the name servlet.jar, whereas Tomcat 5 and later uses servlet-api.jar. This causes problems with PHP's configure script.

PHP Installation





 ./configure --with-servlet=$TOMCAT_HOME --with-java=$JAVA_HOME




Modify your LD_LIBRARY_PATH to include the dynamic library produced in the first step above: 
 LD_LIBRARY_PATH=$PHP_HOME/libs




 export LD_LIBRARY_PATH
As an option, you can put libphp4.so someplace where java is already looking, any place in  System.getProperty("java.library.path"), such as any of:
  /usr/lib/jdk1.5.0_04/jre/lib/i386/client:/usr/lib/jdk1.5.0_04/jre/lib/i386:/usr/lib/jdk1.5.0_04/jre/../lib/i386
Fedora Core 1 Issues with Tomcat 5.5.9, PHP 4.3.11 and jdk1.5.0_03
If make returns an error regarding "enum" while trying to build phpsrvlt.jar, you'll need to edit $PHP_HOME/sapi/servlet/servlet.java and replace enum with xenum.

Start Tomcat
Testing
    <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>
Create a file named test.php in the docBase directory of your webapp.
If everything is working as it should, you will see an informational status page produced by PHP.
