无法使用PHPSpreadsheet生成PHP文件

Question

我目前在WordPress中使用PHPSpreadsheet。在本地一切都很好，但是当我将其传输到服务器时，我的电子表格根本无法工作。单击我的“生成excel”按钮时，它会给我提供一系列字符。

我尝试了许多解决方案，但仍然无法正常工作，并显示了一系列未知字符。

这是我在PHPSpreadsheet中的代码

// Initialize context
const context = React.createContext({ name: "" });

/**
 * My provider component which has it's own state
 * for updating existing context.
 */
const MyProvider = ({ children }) => {
  const [state, setState] = React.useState({ name: "" });
  return (
    <context.Provider value={state}>
      <input
        value={state.name}
        onChange={({ target }) => {
          console.log(target.value);
          setState({ name: target.value });
        }}
      />
      {children}
    </context.Provider>
  );
};



/**
 * Context to consume existing parent component context
 */
const MyConsumer = ({ children }) => {
  return <context.Consumer>{ctx => <MyComponent {...ctx} />}</context.Consumer>;
};

/**
 * provide values as props to your component with lifecycle-methods.
 */
const MyComponent = ({ name }) => {
  const [fetchResult, setResult] = React.useState({});
  React.useEffect(() => {
    console.log("child updated with name: ", name);
    /**
     * Fetch some data and set it to local state
     */
    const mockFetchResult = {
      title: name + `\n${Math.random() * 1024}` // Dummy example to get some random data
    };
    setResult(mockFetchResult);
  }, [name]);
  return <p>{fetchResult.title}</p>;
};
