安装pear和phpdoc
？PHP5.2.17以后版本：
wget http://pear.php.net/go-pear.phar
chmod 700 go-pear.phar
/usr/local/php52/bin/php go-pear.phar
(安装过程同老版本)
which pear查看pear命令位置，并用pear安装phpdoc
/usr/local/php52/bin/pear install phpdoc
如果提示无法下载，则手动下载PHPDoc-0.1.0.tgz
wget http://download.pear.php.net/package/PHPDoc-0.1.0.tgz指定安装：/usr/local/php52/bin/pear install ./PHPDoc-0.1.0.tgz
（完成）

(phpdoc安装完成)
？PHP5.2.17以前 版本：
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/php go-pear.php
出现如下提示：
Welcome to go-pear!
Go-pear will install the 'pear' command and all the files needed by
it. This command is your tool for PEAR installation and maintenance.
Go-pear also lets you download and install the following optional PEAR
packages: PEAR_Frontend_Web-beta, PEAR_Frontend_Gtk2, MDB2.
If you wish to abort, press Control-C now, or press Enter to continue:
回车，出现如下内容：

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 PEAR installation. To change individual locations, type the number in front of the directory. Type 'all' to change all of them or simply press Enter to accept these locations. 1. Installation prefix ($prefix) : /root/downloads/jdk 2. Temporary files directory : $prefix/temp 3. Binaries directory : $prefix/bin 4. PHP code directory ($php_dir) : $prefix/PEAR 5. Documentation base directory : $php_dir/docs 6. Data base directory : $php_dir/data 7. Tests base directory : $php_dir/tests 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 PEAR installation. To
change individual locations, type the number in front of the
directory. Type 'all' to change all of them or simply press Enter to
accept these locations.
1. Installation prefix ($prefix) : /root/downloads/jdk
2. Temporary files directory : $prefix/temp
3. Binaries directory : /usr/bin
4. PHP code directory ($php_dir) : /usr/local/php/bin
5. Documentation base directory : /usr/local/php/docs
6. Data base directory : /usr/local/php/data
7. Tests base directory : $php_dir/tests
1-7, 'all' or Enter to continue:
到这里，再回车：
