输出这个数组php

Question

有人可以帮我输出这个数组。不知道如何获得答案数组输出？

这是阵列输出：

这就是我到目前为止所做的：

foreach($questions as $question) {
    echo $question['question'];

    foreach($question['answer'] as $answer) {
            'HOW DO I GET THE ANSWERS WHICH IS IN ARRAY'
    }

Answer 1

根据您的数组，在内部internal sealed class KeyboardInputEvents : InputEvents { public KeyboardInputEvents(DispatcherEvents dispatcherEvents) : base(dispatcherEvents) { EventManager.RegisterClassHandler(typeof(Window), UIElement.PreviewGotKeyboardFocusEvent, new KeyboardFocusChangedEventHandler(GotKeyboardFocus), true); } private void GotKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e) { var currentFrameworkElement = ((FrameworkElement)e.NewFocus); System.Diagnostics.Debug.WriteLine(currentFrameworkElement.Name); DependencyPropertyDescriptor desc = DependencyPropertyDescriptor.FromProperty(FrameworkElement.TagProperty, typeof(FrameworkElement)); desc.AddValueChanged(currentFrameworkElement, OnPropChanged); } private void OnPropChanged(object sender, EventArgs e) { //Changes were made, do something } } 循环中交换$question['answer'] $question['answers']（注意复数形式的答案）。

Answer 2

foreach($question as $question) {
echo $question['question'];

foreach($question['answers'] as $answer) {
        echo $answer;
}

签出变量名称（$ question，$ questions，$ question ['answers']，$ question ['answer']）
