我觉得这很奇怪，但我似乎无法让PHP报告错误。PHP将不会报告错误
我正在制作一个类来检查和格式化CMS以外的某些结果，以便在不必创建自定义插件（由于时间限制）的情况下实现更高的过滤能力。
我在页面顶部包含这两行。
//error_reporting(E_ALL);
//ini_set('display_errors', '1');
我已经切换每个并尝试使用两个，没有效果。我的php.ini显示display_errors与html_errors相同。 error_reporting设置为1.
对于旧代码，我有它的工作原理，错误报告显示通知和错误。尽管在某些情况下我遇到了同样的问题，但问题是由于在函数外部设置变量导致无法在函数内调用该函数而无需将其作为函数参数。这就是为什么我决定改用班级来避免这个问题。
我想做一个简单的类来做到这一点，并输出结果为JSON。我的PHP并不完美，但如果我至少得到一个错误，我可以轻松地诊断出错的地方。在这种情况下，我无法让PHP甚至显示回声，更不用说任何数据/错误。我得到的只是一张纯白色的页面。这里是我正在使用的完整代码，因为我正在更新它的过程中，所以这是一团糟。

我知道可能有一些非常明显的错误。但没有PHP错误，我无法缩小它。我希望对于有更多PHP经验的人来说，这个问题有一个明显的问题。
当你说你正在包括这些行，我认为你是从他们开始删除//？ – bhttoan
