在构造函数php上将另一个类的array属性推入元素

Question

大家好，祝贺您的出色工作， 我的问题是：我想在不实例化“所有”类的情况下将一个对象从一个类的构造函数（课程）推到另一个类（全部）的数组属性（课程）。

我试图做这样的事情All :: array_push（$ Courses，$ this）

课程课程

<?php
class Course
{
    public $Title;
    public $Stream;
    public $Type;
    public $StartDate;
    public $EndDate;


    function __construct($title,$stream,$type,$startDate,$endDate)
    {
        $this->Title = $title;
        $this->Stream = $stream;
        $this->Type = $type;
        $this->StartDate = $startDate;
        $this->EndDate = $endDate;
        //This is C# way 
        All.Courses.Add(this);
        //I tried to do something like this 
        //All::array_push($Courses,$this) but not worked
    }
}
?>

所有班级

<?php

class All
{
    public static $Students = array();
    public static $Assignments = array();
    public static $Trainers = array();
    public static $Courses = array();
    public static $AllCoursesWithTheirStudents = array();
    public static $AllCoursesWithTheirTrainers = array();
    public static $AllCoursesWithTheirAssignments = array();
    public static $AllStudentsWithTheirAssignments = array();
?>
