如何以样本方式将数组更改为html表？

Question

I have a dynamic array :

Array
(
    [user1] => Array
        (
            [012014] => 6788
            [022014] => 11141
            [032014] => 6143
            [042014] => 936
            [052014] => 936
        )

    [user2] => Array
        (
            [012014] => 9
            [022014] => 25
            [032014] => 37
            [042014] => 17
            [052014] => 16
        )

)

And I want to display it like this :

Users |              Months
      |---------------------------------
      |012014|022014|032014|042014|052014
------------------------------------------
user1 | 6788 | 11141| 6143 |  936 |  936
-------------------------------------------
user2 |   9  |   25 |   37 |   17 |  16 

I can't seem to work it out! Here's what I've been trying :

echo "<table>";

foreach($month_all as $site=>$value){
   echo "<tr>";
   echo "<td>$site</td>";
   foreach ($value as $column) {
      echo "<td>$column</td>";
   }
   echo "</tr>";
}    
echo "</table>";

Any way I can do it in a clean way ?

Answer 1

Use two loops: one for displaying all the key values. One for displaying all the values of the users. This version uses <th> to handle the table headers and takes care of the indentation properly because it's using the alternative foreach style.

<table>
    <tr>
        <th>User</th>
        <th colspan="5">Months</th>
        <tr>
            <th></th>
            <?php foreach ($month_all['user1'] as $key): ?>
                <td><?= $key ?></td>
            <?php endforeach ?>
        </tr>
    </tr>
    <?php foreach ($month_all as $site => $value): ?>
        <tr>
            <td><?= $site ?></td>
            <?php foreach ($value as $column): ?>
                <td><?= $column ?></td>
            <?php endforeach ?>
        </tr>
    <?php endforeach ?> 
</table>
