Laravel 5.6 how to read text file line by line
提问by mr.boris
Without Laravel I can use simple code to read text file by line:
如果没有 Laravel，我可以使用简单的代码逐行读取文本文件：
$file = fopen("whatever/file.txt", "r") or exit("Unable to open file!");
while(!feof($file)) {
echo fgets($file). "<br>";
}
fclose($file);
With Laravel this simple thing becomes overwhelming due to local file storage location.
对于 Laravel，由于本地文件存储位置，这个简单的事情变得势不可挡。
I.e. I can get file contents with Storage::get('whatever/file.txt')method, but how to get just a file and then read it in a loop?
即我可以使用Storage::get('whatever/file.txt')方法获取文件内容，但是如何仅获取文件然后循环读取它？
I've tried to use File::get('whatever/file.txt')method but get an error: File does not exist at path.
我尝试使用File::get('whatever/file.txt')方法但得到一个错误：File does not exist at path。

You can get your file like this:
您可以像这样获取文件：
$file = fopen(storage_path("whatever/file.txt"), "r");
This will result in a path similar to this
'/var/www/storage/whatever/file.txt'or '/var/www/foo/storage/whatever/file.txt'if you are serving multiple websites from the same server, it will depend on your setup, but you get the gist of it. Then you can read your file;
这将产生与此类似的路径，
'/var/www/storage/whatever/file.txt'或者'/var/www/foo/storage/whatever/file.txt'如果您从同一服务器为多个网站提供服务，这将取决于您的设置，但您已了解其要点。然后你就可以读取你的文件了；
while(!feof($file)) {
echo fgets($file). "<br>";
}
fclose($file);

You need to know where your file lives. You also need a path to get there. E.g., if your file is located in the storage folder, you could do
您需要知道您的文件所在的位置。您还需要一条通往那里的道路。例如，如果您的文件位于存储文件夹中，您可以这样做
File::get(storage_path('whatever/test.txt'));
dd($contents);

So confusing!
好纠结！
My file was in the folder storage/app/whatever/file.txtbut Laravel storage("whatever/file.txt")method recognizes it as storage/whatever/file.txtpath.
我的文件在文件夹中，storage/app/whatever/file.txt但 Laravelstorage("whatever/file.txt")方法将其识别为storage/whatever/file.txt路径。
As I said before it is overwhelming and confusing a lot.
正如我之前所说，它是压倒性的，而且很混乱。
So, fopen('storage/app/whatever/file.txt')works for me.
所以，fopen('storage/app/whatever/file.txt')对我有用。
