In Linux, the path separator is /. In Windows, it is either \or /. So just use forward slashes and you will be fine.
在 Linux 中，路径分隔符是/. 在 Windows 中，它是\或/。所以只要使用正斜杠就可以了。
APPLICATION_PATH . '/logs/app.log'

You can also use DIRECTORY_SEPARATORconstant instead of \or /.
Usually you'll want to redefine it to have shorter name, like
您也可以使用DIRECTORY_SEPARATOR常量代替\或/。通常你会想要重新定义它以获得更短的名称，比如
define('DS', DIRECTORY_SEPARATOR);
$filename = APP . DS . 'logs' . DS . 'file.txt';

if you want to communicate two or more app of your site, this trick will serve you much
如果你想交流网站的两个或更多应用程序，这个技巧会对你很有帮助
$ Document_root = realpath ( \ filter_input ( INPUT_SERVER , ' DOCUMENT_ROOT '));
this is to convert the route you back real path and then just have to navigate between directories with the DIRECTORY_SEPARATOR without worrying about the operating system installed on your machine or web server
这是为了转换您返回真实路径的路线，然后只需使用 DIRECTORY_SEPARATOR 在目录之间导航，而不必担心安装在您的机器或 Web 服务器上的操作系统
