使用php-java-bridge让PHP5支持java：
一、下载：
最新的版本是：php-java-bridge_6.1.2.1.tar.gz
但不能使用这个版本，因为这个版本中缺少一个函数：java_require
二、首先说明一下安装不成功的情况：
解压：
tar zxvfphp-java-bridge_5.5.4.1.tar.gz
进入目录：
cd php-java-bridge-5.5.4.1/
执行phpize：
/usr/local/php/bin/phpize
编译：
./configure --with-java=$JAVA_HOME--with-php-config=/usr/local/php/bin/php-config
编译的过程和结果都是没问题的，但接下来的make操作就要注意了：
make
报错：
phpdoc -j -c PHPDocConfig.ini>/dev/null
/bin/sh: phpdoc: command notfound
make[1]: *** [JavaRaw.inc] 错误127
make[1]: Leaving directory`/root/downloads/jdk/php-java-bridge-5.5.4.1/server'
make: ***[/root/downloads/jdk/php-java-bridge-5.5.4.1/modules/stamp]错误 2
错误信息中提示没有phpdoc 命令。
在网上查阅了大量资料，知道phpdoc命令是安装phpDocumentor后生成的，而phpDocumentor的安装又是有php的pear模块完成的。
三、安装pear，为安装phpDocumentor做准备
根据网络提供的大量资料显示，所以我们首先安装pear：
同样查阅了大量的网络资料来完成。
安装pear需要使用php命令来执行一个go-pear.php的文件来完成：
go-pear.php文件的获取：
访问：http://pear.php.net/go-pear
将整个网页内容复制下来并存储为go-pear.php即可。
我们这里可以使用vim命令建立go-pear.php文件，将内容复制进去，保存，增加执行权限即可。
用php命令执行go-pear.php：
/usr/local/php/bin/phpgo-pear.php
出现如下提示：
Welcome to go-pear!
Go-pear will install the 'pear' command andall the files needed by
it.
Go-pear also lets you download and installthe following optional PEAR
packages: PEAR_Frontend_Web-beta,PEAR_Frontend_Gtk2, MDB2.
If you wish to abort, press Control-C now, or press Enter tocontinue:
回车，出现如下内容：
HTTP proxy (http://user:password@proxy.myhost.com:port), orEnter for none::
再回车，出现如下内容，提示你安装位置：
Below is a suggested file layout for your new PEARinstallation.
change individual locations, type the number in front of the
directory.
accept these locations.
1-7, 'all' or Enter to continue:
我们可以在命令行后输入1-7和all或者直接回车继续，
我们这里选择输入all，回车。
上一步选择all以后，就要对每一项的安装目录进行定义，这个根据变量提示来确定，这里之定义了四项，定义一项回车一次：
1-7, 'all' or Enter to continue: all
Installation prefix ($prefix) [/root/downloads/jdk] :
Temporary files directory [$prefix/temp] :
Binaries directory [$prefix/bin] :/usr/bin
PHP code directory ($php_dir) [$prefix/PEAR] : /usr/local/php/bin
Documentation base directory [$php_dir/docs] : /usr/local/php/docs
Data base directory [$php_dir/data]: /usr/local/php/data
Tests base directory [$php_dir/tests] :
回车后，返回刚才定义的信息：
Below is a suggested file layout for your new PEARinstallation.
change individual locations, type the number in front of the
directory.
accept these locations.
1-7, 'all' or Enter to continue:
到这里，再回车：
The following PEAR packages are bundled with PHP:PEAR_Frontend_Web-beta,
PEAR_Frontend_Gtk2, MDB2.
Would you like to install these as well? [Y/n] :
输入Y，继续：

******************************************************************************
WARNING!
contain the PEAR PHP directory you just specified:

到这里提示如下，提示是否更改php.ini文件

四、用pearlist可以查看安装了的pear包：
Package
Archive_Tar
Config
Console_Getopt
HTML_Template_IT
MDB2
MIME_Type
PEAR
PEAR_Frontend_Web0.7.4
Structures_Graph
四、安装完了pear后，使用pear来安装PhpDocumentor
首先查找到pear安装位置：
find / -name pear
结果：
/usr/bin/pear
执行安装：
/usr/bin/pear installPhpDocumentor
Did not download optional dependencies:pear/XML_Beautifier, use --alldeps to downloadautomatically
pear/PhpDocumentor can optionally usepackage "pear/XML_Beautifier" (version >=1.1)
downloading PhpDocumentor-1.4.3.tgz...
Starting to downloadPhpDocumentor-1.4.3.tgz (2,423,486 bytes)
..........
当出现如下信息的时候就说明phpdoc安装完成了：
install ok:channel://pear.php.net/PhpDocumentor-1.4.3
注意：可能PhpDocumentor-1.4.3的服务器在美国加州，尽管软件只有不到3M，安装过程相当慢，有可能还会断掉，如果出现这样的情况需要多试几次才行。
五、接下来就是重新编译安装php-java-bridge-5.5.4.1了：
进入php-java-bridge-5.5.4.1的目录：
执行phpize
/usr/local/php/bin/phpize
编译：
./configure --with-java=$JAVA_HOME--with-php-config=/usr/local/php/bin/php-config
安装：
make
make install
注意：如果在make 过结束出现错误，那么请执行make clean清理一下，重新编译后，再make 就可以了。
配置：
编辑php.ini文件：
vim/usr/local/apache2/conf/php.ini
添加如下内容：
[Java]
java.java_home="/usr/local/java/jdk1.6/"
java.java="/usr/local/java/jdk1.6/jre/bin/java"
java.log_file="/var/log/php-java-bridge.log"
java.classpath="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/JavaBridge.jar"
java.libpath="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
extension_dir ="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
extension = java.so
重启apache
service httpd restart
