やるきなし

以下のように wp-cli (以下の wp command)を使って WordPress の自動 update を行っているのだが，

#!/bin/sh

wp core update
wp core update-db --network
wp plugin update --all
wp theme update --all
wp core language update

cron から以下のようなエラーメールが届く．

PHP Parse error:  syntax error, unexpected '[' in /somewhere/public_html/wp-content/plugins/multisite-post-duplicator/inc/mpd-functions.php on line 418

Update 後 Multisite Post Duplicator (v1.7.1) (https://wordpress.org/plugins/multisite-post-duplicator/) が正常動作せず，うまく表示がされなくなる．

サーバの PHP のバージョンは以下のとおりで，

% php -v

http://php.net/manual/en/language.types.array.php にある PHP 5.4 形式の配列(array in PHP = ordered map)定義を使っているのが原因．ということで，以下パッチ．
