Returns the target of a symbolic link

readlink ( string $path ) : string

readlink() does the same as the readlink C function.

Returns the contents of the symbolic link path or FALSE on error.

Note: The function fails if path is not a symlink, except on Windows, where the normalized path will be returned.

Version	Description
5.3.0	This function is now available on Windows platforms (Vista, Server 2008 or greater).
