java php common document transfer Configuration mistake

不搞PHP开发的工作很长时间了,最近修改一个原来做的项目要支持调用Java类,开始重操PHP,先解决配置问题再说。不说太多费话。网上的

文章不少,但是都有很多错误的东西在里面,下面我介绍一下我配置全过程与大家分享,如有问题可以虽时联系愿意为你解决。

说明:此文章的正常性只对本文中所提供版本的PHP和JDK有保证,其它版本的未一一试,如有问题及时联系愿与你一起解决相关问题。

安装配置PHP的工作这里就略过(有不会的朋友可以与我联系inber_net@hotmail.com)

测试环境:Windows2003+IIS+PHP Version 4.3.6 JDK 1.4.1_01

下面我先将网上的错误的配置列表罗列如下

错误配置1
java.home = D:\j2sdk14101\
错误结果如下:
can't open D:\j2sdk14101\\lib\tzmappings.
解决办法:
java.home = D:\j2sdk14101\jre

错误配置2
java.class.path ="C:\PHP\extensions\php_java.jar;x:\Java Class文件存目录\
错误结果如下:
Fatal error: Call to a member function on a non-object in E:\inberkong\public_html\phproot\testjava.php on line
错误原因:用户Java class文件没有存放在 x:\Java Class文件存目录\ 中或者x:\Java Class文件存目录\不存在
解决办法:1 确定java.class.path ="C:\PHP\extensions\php_java.jar;x:\Java Class文件存目录\ 正确
2 确定此目录下有在PHP调用的Class文件并确定是正确的

正确的配置如下:

第一步:确定环境正确
默认以上环境配置正确
PHP目录:C:\PHP
JDK目录:D:\j2sdk14101
第二步
找到C:\WINDOWS下的php.ini
1 找到extension_dir并配置 确保其目录上有php_java.jar php_java.dll
extension_dir = "D:\PHP\extensions"
2 找到;extension=php_java.dll将此配置信息前的分号去掉
extension=php_java.dll
3 文件找到[java]之后的东西配置相关内容
[Java]
java.class.path ="C:\PHP\extensions\php_java.jar;C:\PHP\php_for_class\"
java.home = D:\j2sdk14101\jre
java.library = D:\j2sdk14101\jre\bin\server\jvm.dll
java.library.path = C:\PHP\extensions\
第三步

写一个Java文件并编译后放在C:\PHP\php_for_class\
Test.java文件如下:

package Test;
public class Test
{
public String getMessage(String dd)
{
return "Hello PHP ! I am from JAVA." dd;
}
}

写一个PHP文件testjava.php 调用Test包中的Test类

$system = new Java("java.lang.System");
print "Java version=".$system->getProperty("java.version")."
\n";
print "Java vendor=".$system->getProperty("java.vendor")."

\n\n";
print "OS=".$system->getProperty("os.name")." ".
$system->getProperty("os.version")." on ".
$system->getProperty("os.arch")."
\n";

$formatter = new Java("java.text.SimpleDateFormat","EEEE,MMMM dd, yyyy 'at' h:mm:ss a zzzz");
print $formatter->format(new Java("java.util.Date"))."

\n";

$b=new Java("Test.Test");
$x=$b->getMessage("
Hello Java! I am from PHP!");
echo $x;

?>
显示结果:
Java version=1.4.1_01
Java vendor=Sun Microsystems Inc.
OS=Windows XP 5.2 on x86
