在php中设置接受稍有错误答案的测验

php html

在php中设置接受稍有错误答案的测验,php,html,Php,Html,所以最近我研究了PHP，并利用它设置了一个小测验。我的问题是如何让测验接受拼写稍有错误的答案？例如，如果我的测验问阿拉巴马州的首府是什么，有人把蒙哥马利拼错了一点，我怎么能让它仍然算作对的呢？我想对我的测验提出的所有问题都这样做，如果不让我知道的话，我希望我的问题措辞足够好。这是我目前正在使用的代码，是的，它被设置为三个文件，因为我发现将它放在一个文件中很复杂，我希望得到关于我拥有的多个文件的答案，如果可能的话，我不希望在一个页面上显示所有php代码的示例。代码：列出州和首都的代码，不是完整列

所以最近我研究了PHP，并利用它设置了一个小测验。我的问题是如何让测验接受拼写稍有错误的答案？例如，如果我的测验问阿拉巴马州的首府是什么，有人把蒙哥马利拼错了一点，我怎么能让它仍然算作对的呢？我想对我的测验提出的所有问题都这样做，如果不让我知道的话，我希望我的问题措辞足够好。这是我目前正在使用的代码，是的，它被设置为三个文件，因为我发现将它放在一个文件中很复杂，我希望得到关于我拥有的多个文件的答案，如果可能的话，我不希望在一个页面上显示所有php代码的示例。代码：

列出州和首都的代码，不是完整列表，而是示例：

<?php
$states = Array();
$capitals = Array();
$states[]="Alabama";
$capitals[]="Montgomery";
$states[]="Alaska";
$capitals[]="Juneau";
$states[]="Arizona";
$capitals[]="Phoenix";
$states[]="Arkansas";
$capitals[]="Little Rock";
$states[]="California";
$capitals[]="Sacramento";
$states[]="Colorado";
$capitals[]="Denver";
$states[]="Connecticut";
$capitals[]="Hartford";
$states[]="Delaware";
....etc
   ?>

测验基础的实际主代码：

<!DOCTYPE html>
<html>
<head>
<title>State capital quiz: ask</title>
</head>

<body>
<h1>State Capital Quiz </h1><p>
<?php
$saywhich=@$_GET['saywhich'];
if ($saywhich){
  include("statecapitals.php");
  $which=$_GET['which'];
  $choice=rand(0, sizeOf($states)-1);
   if ($which=='state') {
     $state = $states[$choice];
     print("What is the capital of $state?<br>");
     print("<form action='statecapquizcheck.php' method='get'>\n");
     print("<input type='text' name='capital'><br>\n");
     print("<input type='hidden' name='which' value=$which>\n");
     print("<input type='hidden' name='choice' value=$choice>\n");
     print("<input type='submit' value='Submit Answer'>");
     print("</form>\n");
   }

     $capital = $capitals[$choice];

我希望你有足够的时间独自玩这个，因为这是你学习的方式
如果你自己花了时间来破解这个问题，那么我将为你从中收集到的任何东西提交这个脚本。我采用了你的方案，并编写了一个程序脚本来进行试验；我对soundex（）
很好奇。是的，这是一个传呼机。。。我通常不会这样做，因为我会使用类，所以它是单元可测试的
这在顶部使用了PHP的约定；HTML在底部。这有助于实现逻辑和表示的分离
html可能工作，也可能不工作；这是未经测试的
FWIW，我发现soundex
是非常、非常、非常宽容的！因此，我使用了变音

对的
对不起，再试一次。。。
你想回答哪一个问题？
首都
陈述
匹配的州或首都是什么
我会考虑函数：SimulasyType，LevsTein，SouthExcel，你必须使用像SunDeX这样的模糊的东西。我还建议对州/首府使用关联数组，即，$capital['Alabama']='Montgomery'。这将确保您的列表不会神秘地偏离一个。@TimMorton是的，我真的应该感谢您的建议，并请您或smith快速解释我将如何实现这些东西。我了解这些东西的用途，但我不知道如何实现类似的东西，这样我的程序就可以检查并继续我从来没有使用过soundex，所以这个链接是我最好的建议。我不确定你的答案是否正确。我向你们致敬，因为你们找到了扩音器，我正在玩soundex，并且已经安装好了，但正如你们所说的那个样，它实际上很糟糕。变音有着更现实的宽恕，我所需要做的就是用甲烷来代替soundex这个词，其他的一切都是以同样的方式设置的。我不确定是否将其标记为正确，因为我不知道您的代码是否有效，尽管您关于变音的建议是yetGlad认为它有帮助的最佳选择
