将PHP二维数组转换为HTML [英] PHP two dimensional array into HTML

问题描述

一个简单的谷歌搜索将揭示使用PHP将二维数组转换为HTML的多种解决方案。不幸的是，这些都没有我正在寻找的答案。

我需要一个将数组转换为HTML表的通用代码片段。大多数例子出错的地方在于，他们假设程序员知道表格字段的名称。我希望此代码是通用的，这样即使我不知道字段名称，也可以使用它。

我可以看到我需要两个循环。一个嵌套在另一个内部。我不确定的是如何获取值，因为我不知道密钥。

最终结果将希望输出html像这样：

p>

 < 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> 
  

请记住我想要一个通用而简单的解决方案。我希望这很清楚。

解决方案

以下代码将查看数组的两个维度并将它们放入一个表中。无论键可能是什么，您都可以看到它。如果他们 do 具有关键名称而不仅仅是索引，则这些值将在 $ key 和 $ subkey 。所以，如果你需要它们，你可以购买它们。

代码：

<$ p $ （2,3,4,5），
key2=>数组（2,3,4,5） ，
key3=>数组（3,4,5,6），
key4=>数组（4,5,6,7））; //有或没有钥匙不会破坏它
$ out =;
$ out。=< table>;
foreach（$ myarray as $ key => $ element）{
$ out。=< tr>;
foreach（$ element as $ subkey => $ subelement）{
$。=< td> $ subelement< / td>;
}
$ out。=< / tr>;
}
$ out。=< / table>;

echo $ out;

结果：

如果您希望将键看作标题，您可以在 echo< table>; 行后添加此代码：

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

导致：

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.

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.

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.

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>

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

解决方案

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.

The code:

$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;

The result:

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>";
