[英]PHP calling to a constant using text + variable
I'm creating an application for my mother so she can play quizmaster. 我正在为我的母亲创建一个应用程序,以便她可以玩测验大师。 Since I have to play as on of the canditates, I cannot know the answers + questions.
由于我必须像候选人一样参加比赛,所以我不知道答案和问题。
My solution to this was, creating a constant page so she could fill those out without breaking my code. 我对此的解决方案是,创建一个恒定的页面,以便她可以在不破坏我的代码的情况下填写这些页面。 The display of my page would just be a question with a spoiler tag containing the answer.
我页面的显示只是一个带有包含答案的破坏标签的问题。
Now comes my question, I'm not sure if this is possible, but how do I implement this? 现在是我的问题,我不确定是否可行,但是如何实现呢? I thought about giving an ID to the page (through URL) so I can change the constants to Question_1, Question_2 etc. This way she can add as many questions as she want without me having to make more pages.
我考虑过给页面提供一个ID(通过URL),以便可以将常量更改为Question_1,Question_2等。这样,她可以根据需要添加任意多个问题,而无需创建更多页面。
My page code would look like this: 我的页面代码如下所示:
$page = $_GET['id'];
<div class="spoiler">
<input type="button" onclick="showSpoiler(this);" value="Show/Hide" />
<div class="inner" style="display:none;">
<?php echo ANSWER_1; ?>
</div>
</div>
Ofcourse, QUESTION . 当然,问题。 $page does not work.
$ page不起作用。 (use of undefined constant QUESTION).
(使用不确定的常数QUESTION)。 Is it possible to create the application in the way I just described?
是否可以按照我刚才描述的方式创建应用程序?
My bad, I found the solution: 我不好,我找到了解决方案:
just use 只是使用
$constant_name = 'QUESTION' . $page;
echo constant($constant_name);
