PHP安装扩展的方式：

一、重新编译

进入PHP源码目录./configure --prefix=/usr/local/php ...[其他编译参数]

二、通过phpize添加扩展

进入PHP源代码扩展应用目录ext，例如：

/usr/local/src/EZHTTP-master/soft/php-5.3.27/ext/pcntl/

在pcntl目录下执行phpize命令然后在configure，运行结果如下：

最后修改php.ini配置文件，在最后一行添加，然后重启apache

extension=pcntl.so

三、有些扩展可以通过pecl命令添加扩展

例如安装Libevent扩展直接输入命令pecl install Libevent会在目录

/usr/local/php/lib/php/extensions/no-debug-zts-20090626/

下生成Libevent.so，最后修改配置文件php.ini(同上一个方法）
