これは奇妙に感じますが、php にエラーを報告させることができないようです。
カスタムプラグインを作成しなくても (時間の制約により) より優れたフィルター機能を使用できるように、CMS の外部でいくつかの結果をチェックしてフォーマットするクラスを作成しています。
この 2 行をページの上部に含めています。
//error_reporting(E_ALL);
//ini_set('display_errors', '1');
それぞれを切り替えて、両方を使用してみましたが、効果はありません。私のphp.iniは、display_errorsがオンであり、html_errorsと同じであることを示しています。error_reporting は 1 に設定されます。
古いコードでは動作し、エラー報告には通知とエラーが表示されます。場合によっては同じ問題に遭遇しましたが、関数の外部で変数を設定すると、関数のパラメーターにしないと関数内で呼び出すことができなくなったためです。これが、この問題を回避するためにクラスに切り替えることにした理由です。
これを行う単純なクラスを作成し、結果を JSON として出力しようとしています。私のphpは完璧ではありませんが、少なくともエラーが発生した場合、何が問題なのかを簡単に診断できます. この場合、データ/エラーは言うまでもなく、phpにエコーを表示させることさえできません。私が得るのは真っ白なページだけです。これが私が使用している完全なコードです。更新中なので混乱しています。

おそらくいくつかの非常に明白な間違いがあることを私は知っています。しかし、php エラーがなければ、絞り込むことはできません。PHPの経験が豊富な人にとって、この問題が明らかに修正されることを願っています。
