检查数组变量是否等于不区分大小写的表单帖子名称并确定PHP中的德语定冠词

Question

我建立了一个表格，要求你用德语写一个单词，它会告诉你应该使用哪个定冠词。

我使用了三个问题的数组：

• Cross check if multiple variable are equal in php
• Check if two arrays have the same values
• PHP - Check if two arrays are equal

这是我的代码：

<form action="index.php" method="post">
  <input type="text" class="form-control" id="word" name="word" placeholder="Word">    
  <button type="submit" class="btn btn-secondary">See</button>    
</form>

<?php 
 if ($_SERVER['REQUEST_METHOD'] === 'POST') 
 {

  $word = $_POST["word"];

  $das = ["Kind", "Licht", "Mädchen"];
  $der = ["Hund", "Kater", "Mann", "Storm", "Winter"];
  $die = ["Dame", "Frau", "Katze"];

  sort($word);
  sort($das);
  sort($der);
  sort($die);

  if ($word == $das)
  {
     echo "It is a <b>das</b>.";
  }

  elseif ($word == $der) 
  {
     echo "It is a <b>der</b>.";
  }

  else 
   {
     echo "It is a <b>die</b>.";
   }
 }

?>

Answer 1

看来您需要in_array 函数，而根本不需要sort：

<form action="index.php" method="post">
  <input type="text" class="form-control" id="word" name="word" placeholder="Word">    
  <button type="submit" class="btn btn-secondary">See</button>    
</form>

<?php 
 if ($_SERVER['REQUEST_METHOD'] === 'POST') 
 {

  $word = $_POST["word"];

  $das = ["Kind", "Licht", "Mädchen"];
  $der = ["Hund", "Kater", "Mann", "Storm", "Winter"];
  $die = ["Dame", "Frau", "Katze"];

  if (in_array($word, $das))
  {
     echo "It is a <b>das</b>.";
  }

  elseif (in_array($word, $der)) 
  {
     echo "It is a <b>der</b>.";
  }

  elseif (in_array($word, $die))  
  {
     echo "It is a <b>die</b>.";
  }
 }

?>

Answer 2

你可以用这个

$word = $_POST["word"];
$word=explode(" ",$word);
$das = ["Kind", "Licht", "Mädchen"];
$der = ["Hund", "Kater", "Mann", "Storm", "Winter"];
$die = ["Dame", "Frau", "Katze"];
$das = array_map('strtolower', $das);
$der = array_map('strtolower', $der);
$die = array_map('strtolower', $die);
$word = array_map('strtolower', $word);

Answer 3

你可以试试这个

<?php 
if ($_SERVER['REQUEST_METHOD'] === 'POST') 
{

    $word = $_POST["word"];
    $word=explode(" ",$word);
    $das = ["Kind", "Licht", "Mädchen"];
    $der = ["Hund", "Kater", "Mann", "Storm", "Winter"];
    $die = ["Dame", "Frau", "Katze"];

    $check1 = ($word == $das); 
    $check2 = ($word == $der); 
    if ($check1==true)
    {
        echo "It is a <b>das</b>.";
    }

    elseif ($check2==true) 
    {
        echo "It is a <b>der</b>.";
    }

    else 
    {
        echo "It is a <b>die</b>.";
    }
}

?>

由于这是您要经常解析的内容，因此请将小写的单词存储在您的脚本中。不要使用排序，如果您有很多单词（并且不打算使用某种数据库），请将它们存储为数组键并使用isset()。

我还冒昧地概括了检查不同类型的代码，这样您就不必在下面进一步区分每种类型的词组（.. 所以将来它会变得微不足道添加新组，例如检测各种形式的动词）。

实现（仅检查请求方法是否为 POST 是不够的 - 最好检查是否设置了 POST var）：

<form action="index.php" method="post">
  <input type="text" class="form-control" id="word" name="word" placeholder="Word">    
  <button type="submit" class="btn btn-secondary">See</button>    
</form>

<?php 
if (!empty($_POST["word"])) 
{
  $word = strtolower($_POST["word"]); // be aware, this might not be locale aware for german letters. Look at IntlChar::toLower for proper support with UTF-8.

  $dictionary = [
    "das" => ["kind", "licht", "mädchen"],
    "der" => ["hund", "kater", "mann", "storm", "winter"],
    "die" => ["dame", "frau", "katze"];
  ];

  $found = false;

  foreach ($dictionary as $group => $words)
  {
    if (in_array($words, $word)) 
    {
      echo "It is a <b>" . $group . "</b>.";
      $found = true;
      break;
    }
  }

  if (!$found)
  {
    echo "Not found.";
  }
}
