Please become accustomed to provide decent context info of your problem.

It is always helpful to carefully and detailedly phrase a request, and to support it with system info like OS and shell, related environment (variables, directory structures, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two including your own attempts at a solution, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.

Where are you stuck? Running your given script yields
Code:
Key:  /home/myuser 
Key:  /etc 
Key:  /usr/local 
Key:  /usr

on my system. Even the exotic ${arr[$i]+7} doesn't give an error message (but doesn't evaluate to something sensible either) .

xdg-user-dirs-update

XDG-USER-DIRS-UPD(1)						   User Commands					      XDG-USER-DIRS-UPD(1)

NAME

       xdg-user-dirs-update - Update XDG user dir configuration

SYNOPSIS

       xdg-user-dirs-update [OPTION...] [--set NAME PATH...]

DESCRIPTION

       xdg-user-dirs-update updates the current state of the users user-dirs.dir. If none existed before then one is created based on the system
       default values, or falling back to the old non-translated filenames if such directories exists. The list of old directories used are:
       ~/Desktop, ~/Templates and ~/Public.

       If an old configuration exists it is updated with any new default directories. Additionally, any configured directories that point to
       non-existing locations are reset by pointing then to the users home directory. This typically happens when the users removed the directory,
       so they likely don't want to use it anymore.

       On the first run a user-dirs.locale file is created containing the locale that was used for the translation. This is used later by gui
       tools like xdg-user-dirs-gtk-update to detect if the locale was changed, letting you to migrate from the old names.

       xdg-user-dirs-update is normally run automatically at the start of a user session to update the XDG user dirs according to the users
       locale.

OPTIONS

       The following options are understood:

       --help
	   Print help output and exit.

       --force
	   Update existing user-dirs.dir, but force a full reset. This means: Don't reset nonexisting directories to HOME, rather recreate the
	   directory. Never use backwards compatible non-translated names. Always recreate user-dirs.locale.

       --dummy-output PATH
	   Write the configuration to PATH instead of the default configuration file. Also, no directories are created.

       --set NAME PATH
	   Sets the XDG user dir with the given name.

	   NAME should be one of the following:
	       DESKTOP
	       DOWNLOAD
	       TEMPLATES
	       PUBLICSHARE
	       DOCUMENTS
	       MUSIC
	       PICTURES
	       VIDEOS

	   PATH must be an absolute path, e.g.	$HOME/Some/Directory.

FILES

       The XDG user dirs configuration is stored in the user-dirs.dir file in the location pointed to by the XDG_CONFIG_HOME environment variable.

ENVIRONMENT

       The XDG_CONFIG_HOME environment variable determines where the user-dirs.dirs file is located.

SEE ALSO

       xdg-user-dir(1), user-dirs.dirs(5), user-dirs.defaults(5), user-dirs.conf(5).
