In CLI $_SERVER['DOCUMENT_ROOT'] is not working. How can I fix this? Is there any other option available. I cannot use relative paths, because files are in various directories.
推荐答案
$ _ SERVER包含标头，这些标头在CLI中不可用. Web服务器定义文档根目录.在CLI中，您没有使用Web服务器，因此没有文档根目录.
$_SERVER contains headers which won't be available in the CLI. The web server defines the document root. In the CLI, you aren't using a web server, so there is no document root.
您可以尝试依赖环境变量，前提是它们是由Shell设置的.
You can try to rely on environmental variables, assuming they are set by your shell.
例如，PWD代表当前目录，HOME代表用户的主目录.
For instance, PWD represents the current directory and HOME represents the user's home directory.
$pwd = getenv('PWD');
$home = getenv('HOME');
您还可以使用__FILE__或__DIR__ 魔术常数 尝试描述您当前所在的路径.
You can also use __FILE__ or __DIR__ magic constants to try and depict the path you are currently in.
