在依賴注入裡如何進行多組件間的調用

room['teacher'] = $teacher;    }    function addStudents($student){        $this->room['student'] = $student;    }}class Teacher{    public $name='AAAA';    public $room=[];    function __construct($room){        $this->room = $room;    }    function sayHello(){        echo ' hello '.$this->room['student']->name.'  student '.PHP_EOL;    }}class Student{    public $name = 'BBB';    public $room=[];    function __construct($room){        $this->room = $room;    }    function sayHello(){        echo ' hello '.$this->room['teacher']->name. ' teacher '.PHP_EOL;    }}$Classroom = new Classroom;$Classroom->addTeacher( new Teacher($Classroom->room) );$Classroom->addStudents( new Student($Classroom->room) );$Classroom->room['teacher']->sayHello();$Classroom->room['student']->sayHello();

我用容器將所有的應用組件包起來，然後，當應用組件之間調用的時候，就會有這樣的問題。

前面註冊進去的應用組件無法調用後面註冊的應用，但是後面註冊的應用是可以調用前面的。

那麼如果說，前面的要使用後面的應用，這個問題怎麼解決呢？

回複內容：

room['teacher'] = $teacher;    }    function addStudents($student){        $this->room['student'] = $student;    }}class Teacher{    public $name='AAAA';    public $room=[];    function __construct($room){        $this->room = $room;    }    function sayHello(){        echo ' hello '.$this->room['student']->name.'  student '.PHP_EOL;    }}class Student{    public $name = 'BBB';    public $room=[];    function __construct($room){        $this->room = $room;    }    function sayHello(){        echo ' hello '.$this->room['teacher']->name. ' teacher '.PHP_EOL;    }}$Classroom = new Classroom;$Classroom->addTeacher( new Teacher($Classroom->room) );$Classroom->addStudents( new Student($Classroom->room) );$Classroom->room['teacher']->sayHello();$Classroom->room['student']->sayHello();
