問題描述

一個簡單的谷歌搜索將揭示多種使用 PHP 將二維數(shù)組轉(zhuǎn)換為 HTML 的解決方案.不幸的是，這些都沒有我正在尋找的答案.

A simple Google search will reveal a multitude of solutions for converting a two dimension array into HTML using PHP. Unfortunately none of these has the answers I am looking for.

我想要一段將數(shù)組轉(zhuǎn)換為 HTML 表格的通用代碼.大多數(shù)例子出錯的地方是他們假設程序員知道表的字段的名稱.我希望這段代碼是通用的，這樣即使我不知道字段的名稱，我也可以使用它.

I want a generic piece of code that converts an array into a HTML table. Where most examples go wrong is that they assume the programmer knows the name of the table's fields . I want this code to be generic such that I can use it even if I do not know the name of the fields.

我可以看到我需要兩個循環(huán).一個嵌套在另一個里面.鑒于我不知道密鑰，我不確定如何獲取值.

I can see I need two loops. One nested inside of the other. What I am not sure of is how to get the values out given I don't know the keys.

最終結果有望輸出這樣的html:

The end result will hopefully output html something like this:

<th>
  <td>x/y</td>
  <td> x1 </td>
  <td> x2 </td>
</th>
<tr>
  <td>y1</td>
  <td> x1y1 </td>
  <td> x2y1 </td>
</tr>
<tr>
  <td>y2</td>
  <td> x1y2 </td>
  <td> x2y2 </td>
</tr>

請記住，我想要一個通用且簡單的解決方案.我希望這很清楚.

Please remember I want a generic and simple solution. I hope this is clear.

下面的代碼將遍歷數(shù)組的兩個維度，并將它們變成一個表格.不管 key 是什么，你都會得到它的可視化表示.如果它們確實有鍵名而不僅僅是索引，則這些值將分別在$key 和$subkey 中可用.所以如果你需要它們，你可以擁有它們.

The following code will look through the two dimensions of the array and make them into a table. Regardless of what the key may be, you will get a visual representation of it. If they do have key name and not just an index, the values will be available in $key and $subkey respectively. So you have them if you need them.

代碼:

$myarray = array("key1"=>array(1,2,3,4),
                 "key2"=>array(2,3,4,5),
                 "key3"=>array(3,4,5,6),
                 "key4"=>array(4,5,6,7)); //Having a key or not doesn't break it
$out  = "";
$out .= "<table>";
foreach($myarray as $key => $element){
    $out .= "<tr>";
    foreach($element as $subkey => $subelement){
        $out .= "<td>$subelement</td>";
    }
    $out .= "</tr>";
}
$out .= "</table>";

echo $out;

結果:

如果您想將鍵視為標題，可以在 echo "

If you want to see the keys as headings, you could add this code after the echo "<table>"; line:

echo "<tr>";
foreach($myarray as $key => $element) echo "<td>$key</td>";
echo "</tr>";
