wordpress: how to include a php file in frontend AND admin area (Fatal error: Cannot redeclare myfunction())

I have some troubles to include a file called myplugin_functions.php

This php file contains functions that are required to make some functions work in the wordpress admin area. For that reason I include this file in backend pages using:

include( plugin_dir_path( __FILE__ ) . 'myplugin_functions.php');

This works perfectly.

When I do the same thing on frontend pages, the frontend can access these functions. Great.

But when I then navigate to the backend I get an error message

Fatal error: Cannot redeclare myfunction() (previously declared in /www/htdocs/...) in /www/htdocs/..../myplugin_functions.php on line 28

include_once() makes the problem vanish. But I think wordpress doesn't like including the same php functions for frontend and backend.

Do you know why? What is the best practice to get around this?

Thank you?

wordpress uses the same functions for frontend and backend.....you're prob getting confused with ajax functions which are hooked seperately.

If you are including the file within a function, use require_once/ include_once. If you want the functions to be available to the entire directory, place require_once in your theme functions or plugin file file but then don't include when using functions.

require_once / include_once are actually good practice btw :)
