在PHP中调用JAVA_PHP

安装PHP4.3.5RC3.dev(Win32) Apache 2.0.52(For Win32)和j2sdk 1.4 (For Win32)都不用说了,如果不会安装,请看相关手册。
在PHP配置文件php.ini中找到 " ;extension=php_java.dll " 这上行,并把前面的分号去掉;
再找到:
[Java]
;java.class.path =
;java.home =
;java.library =
;java.library.path =

改为:
java.class.path = "JAVA的CLASS_PATH;(将要放置自己的class文件的目录)d:\java_for_php"
java.home = "JAVA的JAVAHOME"
java.library = "JAVA的JAVAHOME\jre\bin\server\jvm.dll"
java.library.path = "PHP安装目录\extensions\"

修改好后,php.ini 文件必须放在Windows安装目录内,重新启动Apache。

在d:\java_for_php内新建一个PhpCallJava.java ,内容如下:
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;
}
}
编译PhpCallJava.java 生成PhpCallJava.class

新建一个PHP文件,内容如下:
php

$myjava = new Java("PhpCallJava");
echo "Test Result are ".$myjava->test("Hello JAVA, I m PHP.")."
\n
";

$myjava->testString = "JAVA, I gave you a string.";
echo "You have set string is: ".$myjava->testString."
\n
";
echo "My java method reports:".$myjava->GetTestString ()."
\n
";
?>

结果:
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.
