wordpressをアップグレードしたら、function.phpに異常がみられたので解決方法を教えてください。
現在発生している情報だけでなく、元の補足情報に記載してあるphpそのものが怪しいとおもっております。(大変申し訳ございませんが、もし現在の発生しているバグ以外で怪しい箇所がありましたら記載していただけると助かります。）
よろしくおねがいします。

Wordpressの何のファイルなのか探すのに苦労しました。
backwpupでしょうか。
ちゃんと最新版が入っているのでしょうか・・・？
php
1function promise_for?($value);{
ここが怪しいですね。forのあとの「?」や「;」、これを誤って入れてしまったのでは。
php
1function promise_for($value){
が正しそうです。
また、
php
1function task (callable $task) { 2 $queue = queue(); 3 $promise = new Promise ($queue, 'run'); 4 $queue->add (function () use ($task, $promise){ 5 try{ 6 $promise->resolve ($task() ); 7 } catch (\Throwable $e) { 8 $promise->reject($e); 9 } catch (\Exception $e) { 10 $promise->reject($e); 11 } 12 }); 13 return $promise; 14}
でしょうね。
