将代码从Java转换为PHP格式。

我是使用PHP的新手。我正在尝试将Java代码转换为PHP，但收效甚微。特别是将变量类型声明为long，还将类的对象声明为数组。

public class Company extends User implements Serializable {

private static final long serialVersionUID = 8598447488057067508L;

public String id;
public String companyName;
public String companyCode;
public String avatar;

public Price price;
public List<History> history;
public List<Wall> wallpost;

public boolean isFollowing;

public String toString() {
    return "Company [id=" + id 
            + ", companyName=" + companyName 
            + ", companyCode=" + companyCode 
            + ", avatar=" + avatar + "]";
     }
}

在PHP中

 <?php

 include "History.php";
 include "Price.php";
 include "Wall.php";

 class Company extends User implements Serializable {

  private static final  long $serialVersionUID = 8598447488057067508L;// get error here

  public $id;
  public $companyName;
  public $companyCode;
  public $avatar;

  public Price $price;//object of Price Class how to declare this?
  public List<History> $history;//object of History Class how to declare this as a List?
  public List<Wall> $wallpost;//object of Wall Class how to declare this as a list?

  public boolean $isFollowing; //how to assign boolean to this variable?
 }

我相信应该有一种在PHP中强制转换的方法。

谢谢您的帮助。

只是将它们定义为数组，就不能定义类型：

<?php

 include "History.php";
 include "Price.php";
 include "Wall.php";

 class Company extends User implements Serializable {

  // Define as constant, include value in quotes
  const serialVersionUID = "8598447488057067508L";

  public $id;
  public $companyName;
  public $companyCode;
  public $avatar;

  public $price;
  public $history = array();
  public $wall = array();

  public $isFollowing;

  public function __construct()
  {
        // Set price
        $price_obj = new Price();
        array_push($this->price, $price_obj);

        // Set history
        $history_obj = new History();
        array_push($this->history, $history_obj);

        // Set wall
        $wall_obj = new Wall();
        array_push($this->wall, $wall_obj);

        // Assign boolean
        $this->isFollowing = true;

  }
 }
