PHP扩展 - 《config》

《config》扩展是实现将配置选项加载到内存中,优化配置文件加载过程。

建议使用场景:

1、多个项目中需要调用共用的配置,使用config来管理,避免一式多份的拷贝维护。

2、配置选项很多,使用config加载入内存,可以避免PHP每次加载配置文件进行解释执行。


项目地址:http://git.oschina.net/365690485/php_extension_config



注:目前仅测试编译PHP5.3.3,其他版本未测试编译

先来看一个简单的config.ini:
;参数值长度不能超过255

[define]
;============================服务中心域名======================
;消息转发服务器节点一
MSG_SERVER_0            =       http://msg0.10000.cn/
;用户服务中心网址
USER_SERVICE            =       http://user.service.10000.cn/
;消息服务中心网址
MSG_SERVICE             =       http://msg.service.10000.cn/

[config]
max_upload_size          =      2048
login_redirect_url          =     http://login.service.10000.cn/
Copy after login

语法格式:
“;”开头表示注释
[define]下面的选项,表示定义为宏,等同于define(key, value),客户端调用方式:echo MSG_SERVER_0
[config]下面的选项,表示定义为key-value形式的链表,客户端调用方式:echo config('max_upload_size')

建议使用场景:
1、多个项目中需要调用共用的配置,使用config来管理,避免一式多份的拷贝维护。
2、配置选项很多,使用config加载入内存,可以避免PHP每次加载配置文件进行解释执行。



一、安装步骤(centos)
1.安装PHP的开发环境
yum -y install php-devel
Copy after login

2.解压扩展包
tar zxf config.tar.gz
Copy after login

3.进入目录,编译安装
cd config
phpize
./configure --with-php-config=/usr/bin/php-config
make && make install

4.配置php.ini
