php - PHP将不会报告错误

Question

我觉得这很奇怪，但是我似乎无法让php报告错误。

我正在制作一个类，以检查CMS外部的某些结果并设置其格式，以允许更大的过滤功能而不必创建自定义插件(由于时间限制)。

我在页面顶部包括了这两行。

//error_reporting(E_ALL);
//ini_set('display_errors', '1');

我已经切换每个并尝试使用两者，没有效果。我的php.ini显示display_errors处于打开状态，并且与html_errors相同。 error_reporting设置为1。

对于较旧的代码，我可以使用它，并且错误报告会显示通知和错误。尽管在某些情况下确实遇到了相同的问题，但是该问题是由于在函数外部设置变量导致无法在不将其作为函数参数的情况下在函数内调用。这就是为什么我决定切换到类(class)以避免这个问题的原因。

我试图做一个简单的类来做到这一点，并将结果输出为JSON。我的php并不完美，但是如果我至少遇到错误，我可以轻松诊断出问题所在。在这种情况下，我什至无法使php显示回显，更不用说任何数据/错误了。我所得到的只是一张纯白纸。这是我正在使用的完整代码，在我进行更新的过程中一团糟。

我知道可能存在一些非常明显的错误。但是没有php错误，我无法缩小范围。我希望对具有更多php经验的人有一个明显的解决方法。

Answer 1

您确定会遇到错误吗？

也尝试一下:

@ini_set('error_reporting', 'true');
error_reporting(E_ALL | E_STRICT);

您的函数可能是错误的，您编写的函数如下

public function something() {}; <==

写像

public function something() {} 

不能解决您的错误问题，但至少要注意
