php - file_get_contents(): open_basedir restriction in effect

I got a strange error message:

file_get_contents(): open_basedir restriction in effect.
File(/path/to/file) is not within the allowed path(s):
(/Library/WebServer:/var/tmp:/path/to)

As seen, the path to the file has been added in the allowed paths, why does open_basedir restriction remain in effect?

Answer

You’d need to check permissions of /path and /path/to. Somehow it didn’t show You don't have permission to access but this open_basedir restriction in effect message.
