今日应开发需求，想要显示图片的属性信息，于是度娘就告知exif模块可以实现，操作步骤与问题总结吐下；@H_502_1@

一、环境介绍@H_502_1@

[root@ghzz~]#cat/etc/redhat-release
CentOSrelease6.5(Final)
Youhavenewmailin/var/spool/mail/root
[root@ghzz~]#PHP-v

二、查找模块@H_502_1@

方法一：去PHP安装路径下ext目录下都是模块@H_502_1@

cd /root/software/PHP-5.6.14/ext/exif@H_502_1@

###这个模块，应该是PHP安装包内自带的，但是./configure编译安装的时候没有加载的包@H_502_1@

方法二：PHP官网@H_502_1@

PHP官网地址：http://pecl.php.net/packages.php@H_502_1@

@H_502_1@

三、编译安装 （加载模块）@H_502_1@

1）进入PHP存储模块目录@H_502_1@

[root@ghzzlsolesen-pel-56d1b7f]#cd/root/software/PHP-5.6.14/ext/exif
[root@ghzzexif]#ll

2）使用PHPize添加PHP动态模块@H_502_1@

作用：使用PHPize生成@H_502_1@
