我覺得這很奇怪，但我似乎無法讓PHP報告錯誤。PHP將不會報告錯誤
我正在製作一個類來檢查和格式化CMS以外的某些結果，以便在不必創建自定義插件（由於時間限制）的情況下實現更高的過濾能力。
我在頁面頂部包含這兩行。
//error_reporting(E_ALL);
//ini_set('display_errors', '1');
我已經切換每個並嘗試使用兩個，沒有效果。我的php.ini顯示display_errors與html_errors相同。 error_reporting設置爲1.
對於舊代碼，我有它的工作原理，錯誤報告顯示通知和錯誤。儘管在某些情況下我遇到了同樣的問題，但問題是由於在函數外部設置變量導致無法在函數內調用該函數而無需將其作爲函數參數。這就是爲什麼我決定改用班級來避免這個問題。
我想做一個簡單的類來做到這一點，並輸出結果爲JSON。我的PHP並不完美，但如果我至少得到一個錯誤，我可以輕鬆地診斷出錯的地方。在這種情況下，我無法讓PHP甚至顯示回聲，更不用說任何數據/錯誤。我得到的只是一張純白色的頁面。這裏是我正在使用的完整代碼，因爲我正在更新它的過程中，所以這是一團糟。

我知道可能有一些非常明顯的錯誤。但沒有PHP錯誤，我無法縮小它。我希望對於有更多PHP經驗的人來說，這個問題有一個明顯的問題。
當你說你正在包括這些行，我認爲你是從他們開始刪除//？ – bhttoan
