【中文标题】(1/1) FatalErrorException 无法声明比特币类，因为该名称已在 easybitcoin.php 第 4 行中使用

【英文标题】：(1/1) FatalErrorException Cannot declare class Bitcoin, because the name is already in use in easybitcoin.php line 4

【发布时间】：2019-07-09 14:00:51

【问题描述】：

我有 2 个文件都同名 easybitcoin.php 和 Easybitcoin.php

这是它抛出的错误

(1/1) 致命错误异常

无法声明比特币类，因为该名称已在 easybitcoin.php 第 4 行

第 4 行是

class Bitcoin 

如果有人能指出我正确的方向。每次我去点击生成新的钱包地址。 Laravel 抛出这个错误

【问题讨论】：

两个文件是否都定义了Bitcoin 类？请显示完整的错误。

【参考方案1】：

您正在使用两个具有相同名称的类，或者您包含两次相同的类。 假设问题是第一个，您可以为每个文件分配一个命名空间。 然后，如果你需要将第二个类调用到第一个类中，你可以给它一个别名并通过这个来调用它。

file1.php：

namespace App\Something;

class Bitcoin 
    public static doSomething()

file2.php：

namespace App\YouCoolPath;

use App\Something\Bitcoin as YourAlias;

class Bitcoin 
    public function __construct() 
        YourAlias::doSomething();
