How to correct create_function() is deprecated error

After my webhost upgraded to PHP 8.1.2 any posts using CodeColorer would barf at line 4698. Following what’s mentioned here: https://www.php.net/manual/en/function.create-function I corrected it by changing the following in /wp-content/plugins/codecolorer/geshi.php:

            if (!isset($callback_2)) {
                //$callback_2 = create_function('$matches', 'return "[" . str_replace("|", "", $matches[1]) . "]";');
                $callback_2 = function($matches) { return "[" . str_replace("|", "", $matches[1]) . "]"; };
            }

Everything now works again and displays the syntax highlighting.

Hope this helps.
