改為:
              java.class.path = "java的class_path;(將要放置自己的class文件的目錄)d:/java_for_php"
              java.home = "java的javahome"
              java.library = "java的javahome/jre/bin/server/jvm.dll"
              java.library.path = "php安裝目錄/extensions/"

    修改好后，php.ini 文件必須放在windows安裝目錄內，重新啟動apache。

    在d:/java_for_php內新建一個phpcalljava.java ，內容如下：
    public class phpcalljava {
            public string teststring;
           
            public string test (string str) {
                     if (str.equals("")) {
                         return "this is a empty string!";
                     } else {
                         return str;
                     }
            }

             public string getteststring () {
                      return "your string is: " + teststring;
             }
    }
   編譯phpcalljava.java 生成phpcalljava.class

    新建一個php文件，內容如下：
    <?php

           $myjava = new java("phpcalljava");
           echo "test result are <b>".$myjava->test("hello java, i m php.")."</b><br>/n";
 
           $myjava->teststring = "java, i gave you a string.";
           echo "you have set string is: <b>".$myjava->teststring."</b><br>/n";
           echo "my java method reports:<b>".$myjava->getteststring ()."</b><br>/n";
    ?>

    結果:
          test result are hello java, i m php.
          you have set string is: java, i gave you a string.
          my java method reports:your string is: java, i gave you a string.
