Reads the file identified by `file_name` and returns it as a `String`.
|
||||
|
||||
If the file cannot be read, this function returns an empty string.
|
||||
The read transparently takes a shared file lock for the duration of the call. If another worker is writing the same file with `file_put_contents()` or `file_append()`, this read waits for that exclusive write lock to finish, so callers do not manage locks manually.
