Pear是
PHP扩展和
应用库("PHP Extension and Application Repository")的缩写,注意它不是鸭梨,尽管和该水果的发音相同。在安装好php之后，缺省情况下会自动安装pear的部分程序库，我们看看这种情况下如何自行安装更多的应用库。
全自动安装
很简单，只用一行。
PLAIN TEXTCODE:
pear install <package>
<package>应当是你要安装的库名，可以到Pear的站上浏览，相当丰富。也可以用命令行直接查看：
pear remote-list
提示：使用"-o"参数能够自动安装必需的依赖应用库。
手动安装
如果你直接在pear站上
下载了gzip的安装包，可以采用这种安装形式。pear会自动安装这个应用库，不再链接到网上去下载。
PLAIN TEXTCODE:
pear install <file>.tgz
