我已经尝试了很多方法来解决这个问题，但没有工作。以下是我的php.ini文件代码：

[XDebug]
xdebug.mode=debug
xdebug.remote_enable=on
xdebug.start_with_request=yes
xdebug.client_host=host.docker.internal
xdebug.discover_client_host = true
zend_extension = "C:\xampp\php\ext\php_xdebug.dll"

我也尝试过xdebug.profiler_enable=on，但是当我在CMD中运行php -v时，两者都有这个问题：
Xdebug：[配置]设置“xdebug.remote_enable”已重命名，请参见www.example.com上的升级指南https://xdebug.org/docs/upgrade_guide#changed-xdebug.remote_enable（参见：https：//xdebug.org/docs/errors#CFG-C-CHANGED）
下面是我的launch.json文件：

        },
        {
            "name": "Listen for Xdebug 2 (Legacy)",
            "type": "php",
            "request": "launch",
            "port": 9000
        },
        {

            "runtimeArgs": [

                "-dxdebug.remote_autostart=yes"
            ],
            "env": {
                "XDEBUG_CONFIG": "remote_port=${port}"
            }
        },
        {
            "name": "Xdebug Cloud",
            "type": "php",
            "request": "launch",
            "xdebugCloudToken": ""
        },
        {
            "type": "chrome",
            "request": "launch",
            "name": "Launch Chrome against localhost",
            "url": "http://localhost:8080",
            "webRoot": "${workspaceFolder}"
        }
    ],
    "pathMappings": {
        "/var/www/html": "${workspaceFolder}/www",
        "/app": "${workspaceFolder}/app"
    }
}

我还升级了我的PHP和Apache版本。我使用的是XAMPP。
我已经按照安装Xdebug的一步一步的说明，并观看YouTube教程，但似乎没有工作：我的变量、监视和调用堆栈为空，并且代码未调试。
