1、设置常量并绑定容器

2、容器增加设置当前容器的实例和绑定一个类实例当容器

 //设置当前容器的实例public static function setInstance($instance){static::$instance = $instance;}//绑定一个类实例当容器public function bandInstance($abstract, $instance){if ($instance instanceof \Closure) {$this->bind[$abstract] = $instance;} else {if (isset($this->bind[$abstract])) {$abstract = $this->bind[$abstract];}$this->instances[$abstract] = $instance;}return $this;}

3、将常量绑定到容器中

<?php
namespace fm;
class core extends Di{protected $corePath;//核心目录路径protected $rootPath;//项目根目录public function __construct($appPath = ''){}public  function run(){$this->_int();//初始化常量echo '框架运行中';}public function _int(){//获取框架核心路径 都替换/以便兼容linux$path=str_replace("\\","/",__FILE__);//定义常量$this->corePath=dirname(dirname($path));$this->rootPath=dirname($this->corePath);static::setInstance($this);$this->bandInstance('core', $this);var_dump( $this->getInstance());exit;}}
