让Java类在PHP下被支持-PHP教程,PHP技巧

系统环境：

redhat 9.0

apache-1.3.27

mysql3.23-54a-11

php-4.32

j2sdk1.4.1_03

安装配置：

1．mysql使用的是redhat9自带的rpm包，不介绍安装了，jdk的安装也很简单，我们把jdk安装到/usr/java/j2sdk1.4.1_03 并在/etc/profile设置jdk环境参数。

2．编译安装apache

tar zvxf apache_1.3.27.tar.gz

cd apache_1.3.27

./configure –prefix=/usr/local/apache –enable-module=so –enable-shared=max

make

make install

3．编译安装php

tar zvxf php-4.3.2.tar.gz

cd php-4.3.2

./configure –prefix=/usr/local/php –with-mysql \

–with-apxs=/usr/local/apache/bin/apxs \

–with-java=/usr/java/j2sdk1.4.1_03

make

make install

修改/usr/local/apache/conf/httpd.conf

查找

在此范围添加

addtype application/x-httpd-php .php

addtype application/x-httpd-php-source .phps

4．配置php.ini

cp php.ini.dist /usr/local/php/lib/php.ini

vim php.ini

修改如下内容：

[java]

java.class.path = /usr/local/php/lib/php/php_java.jar

java.home = /usr/java/j2sdk1.4.1_03

java.library = /usr/java/j2sdk1.4.1_03/jre/lib/i386/libjava.so

java.library.path =/usr/local/php/lib/php/extensions/no-debug-non-zts-20020429

extension_dir = /usr/local/php/lib/php/extensions/no-debug-non-zts-20020429

extension=java.so

保存退出。

cd /usr/local/php/lib/php/extensions/no-debug-non-zts-20020429

ln –s java.so libphp_java.so 这一步很重要哦！

设置环境变量：

export ld_library_path=/usr/java/j2sdk1.4.1_03/jre/lib/i386:/usr/java/j2sdk1.4.1_03/jre/lib/i386/server

ok!重启一下apache

/usr/local/apache/bin/apachectl start

测试一下，写个测试页test.php

<?

$system=new java("java.lang.system");

//demonstrate property access

print java version=.$system->getproperty(java.version). <br>;

?>

正常的话页面应该能显示：java version=1.4.1_03
