Tomcat解析php的疑问，求解答

Question

在服务器上php的安装：
1。下载php-4.4.2 for windows的压缩包
2。解压缩到D:\software\php442
3。将D:\software\php442增加到环境变量PATH中
4。将php.ini-dist做一个备份，然后重命名为php.ini，修改
extension_dir = "D:\software\php442\extensions"
cgi.force_redirect = 05。Tomcat的配置：
打开conf\web.xml，增加如下一段： <!-- hankjin php -->
 <servlet>
        <servlet-name>cgi</servlet-name>
        <servlet-class>org.apache.catalina.servlets.CGIServlet</servlet-class>
        <init-param>
          <param-name>clientInputTimeout</param-name>
          <param-value>100</param-value>
        </init-param>
        <init-param>
          <param-name>debug</param-name>
          <param-value>0</param-value>
        </init-param>
        <init-param>
          <param-name>executable</param-name>
          <param-value>d:/software/php442/php.exe</param-value>
        </init-param>
        <init-param>
          <param-name>cgiPathPrefix</param-name>
          <param-value>WEB-INF/..</param-value>
        </init-param>
        <load-on-startup>5</load-on-startup>
    </servlet>    <servlet-mapping>
        <servlet-name>cgi</servlet-name>
        <url-pattern>*.php</url-pattern>
    </servlet-mapping>
 <!-- end hankjin php -->6。到server\lib目录，将servlets-cgi.renametojar文件重命名为servlets-cgi.jar
7。到一个Web Application下，新建一个test.php，内容为：
<?php phpinfo();?>
8。重启Tomcat服务器，访问这个test.php，OK
