php ioc and web rest design

三个核心文件

1.公开访问web service配置 config.php

2.管理BEAN，扫描，注册，初始化等流程 ioc.php

3.管理 rest 拦载处理 ws.php

config.php

<?php

    /**

        'TestRef',

    ); 

    /**容器注册类*/

    $_ioc= array();

    $_app_path_index=1;

?>

ioc.php

        $file = $name.$_suffix;

        include_once $file;

        register_bean($name,new $name);

    }

}



/**注册BEAN*/

}



/**获取BEAN*/

function get_bean($name){

    global  $_ioc;

    return  $_ioc[$name];

/**容器注册后期阶段*/
