1.确保引入了 vendor/autoload.php 文件

2.打开composer.json 文件，修改值：

{
    "require": {
        "swoole/ide-helper": "^4.6",
        "phpunit/phpunit": "^9.5",
        "spatie/array-to-xml": "^2.15",
        "fzaninotto/faker": "^1.9",
        "topthink/think-orm": "^2.0",
        "endroid/qr-code": "^4.0"
    },
    "autoload": {
        # 格式"命名空间开头\\": "对应的目录"
        "psr-4": {
            "app\\" : "app/",
            
            
        },
        #要自动加载的文件
        "files":[
            "PHP/helper/file.php",
            
        ]
    }
}
3.在命令行，打开在composer.json 所在目录；执行命令 composer dump-autoload即可
