How to display two table columns per row in php loop
提问by brad
I would like to display data, two columns per row during my foreach. I would like my result to look like the following:
我想在 foreach 期间显示数据，每行两列。我希望我的结果如下所示：
<table>
<tr><td>VALUE1</td><td>VALUE2</td></tr>
<tr><td>VALUE3</td><td>VALUE4</td></tr>
<tr><td>VALUE5</td><td>VALUE6</td></tr>
</table>
Any help would be greatly appreciated.
任何帮助将不胜感激。

$i=0;
foreach ($x as $key=>$value)
{
if (fmod($i,2)) echo '<tr>';
echo '<td>',$value,'</td>';
if (fmod($i,2)) echo '</tr>';
$i++;
}
this will output TR (row) each second time
这将每秒输出 TR（行）
ps: i haven't tested the code, so maybe you will need to add ! sign before fmod, if it doesn't output TR on first iteration, but on second iteration in the beginning...
ps：我还没有测试代码，所以也许你需要添加！在 fmod 之前签名，如果它在第一次迭代时没有输出 TR，而是在开始的第二次迭代中...

You can use array_chunk()to split an array of data into smaller arrays, in this case of length 2, for each row.
您可以使用array_chunk()将数据数组拆分为更小的数组，在这种情况下，每行的长度为 2。
<table>
<?php foreach (array_chunk($values, 2) as $row) { ?>
<tr>
<?php foreach ($row as $value) { ?>
<td><?php echo htmlentities($value); ?></td>
<?php } ?>
</tr>
<?php } ?>
</table>
Note that if you have an odd number of values, this will leave a final row with only one cell. If you want to add an empty cell if necessary, you could check the length of $rowwithin the outer foreach.
请注意，如果您有奇数个值，这将留下最后一行只有一个单元格。如果您想在必要时添加一个空单元格，您可以检查$row外部foreach.

<table>
<?php
$i=0;
foreach ($x as $key=>$value)
{
if (!$i%2) echo '<tr>';
echo '<td>',$value,'</td>';
if ($i%2) echo '</tr>';
$i++;
}
?>
</table>
