PHP-使用间隔列创建动态HTML表
[英]PHP - create dynamic html table with spacer columns
问题描述
I am trying to create a dynamic grid (HTML table) using php. 
我正在尝试使用php创建动态网格（HTML表）。
I need to make a table with 5 columns per row and all the odd columns will have a width of 32% whereas the even columns will be empty but have a width of 2% which is used as spacers. 我需要制作一个每行5列的表，所有奇数列的宽度为32％，而偶数列的宽度为2％，用作间隔符。
I also need it so if any row doesn't have 3 odd columns, it must generate the rest to make 5 even if they are empty. 我也需要它，所以如果任何行没有3个奇数列，即使它们为空，它也必须生成其余的5个。
I've managed to do it so it creates 3 columns of 32% width and adds empty TDs if it needs to be I haven't been able to create the smaller 2% columns. 我设法做到了，所以它创建了3个32％宽度的列，并在需要时添加了空TD，而我还无法创建较小的2％列。
This is going to be used as a table grid for an HTML email 这将用作HTML电子邮件的表格网格
This is what I have working at the minute but only 3 columns 这是我目前的工作，但只有3列
<?php
$test = array(1,2,3,4,5);
$count = 0;
?>
<html>
<head>
<style>
.test {border: 1px solid #ccc;}
</style>
</head>
<body>
<table cellspacing="0" cellpadding="0" border="0" width="650">
<?php foreach($test as $t): ?>
<?php if ($count % 3 == 0) echo "<tr>"; # new row ?>
<td width="32%" class="test">
<p>ddfhfdhfgh</p>
<p>sdgdfgdgd</p>
</td>
<?php $count++; ?>
<?php if ($count % 3 == 0) echo "</tr>\n"; # end row ?>
<?php endforeach; ?>
<?php if ($count % 3 != 0): ?>
<?php while ($count++ % 3): ?>
<td width="32%"> </td>
<?php endwhile; ?>
</tr>
<?php endif; ?>
</table>
</body>
</html>
and I've tried adding this but it makes a mess. 而且我尝试添加它，但是很混乱。
<?php if ($count % 3 == 0) echo "<tr>"; # new row ?>
<?php if ( $count & 1 ): ?>
<td width="32%" class="test">
<p>ddfhfdhfgh</p>
<p>sdgdfgdgd</p>
</td>
<?php else: ?>
<td width="2%"> </td>
<?php endif; ?>
<?php $count++; ?>
All i need is a table with 3 large columns and 2 spacer columns in between 我需要的是一张桌子，中间有3个大栏和2个间隔栏

I think this should do the trick. 我认为这应该可以解决问题。
You were making it a bit more complex than it needs to be. 您使它变得比需要的复杂一些。
First you can make use of the foreach syntax like this foreach ($array as $index => $value) so you dont need to keep your own counter. 首先，您可以使用像foreach这样的foreach语法foreach ($array as $index => $value)因此您不需要保留自己的计数器。
Second, you basically want every other column to take a different size so use % 2 and not % 3 and a simple if then else construct. 其次，您基本上希望其他所有列都采用不同的大小，因此请使用% 2而不是% 3并使用一个if then else构造的简单构造。
It also makes code easier to read if you dont use the php start and stop tags <?php ... ?> around every line of PHP, if you have more than one line of consecutive php code just use one to start the interpreter above the first line and one after the last line of PHP code. 如果您在PHP的每一行中不使用php开始和停止标记<?php ... ?> ，它也使代码更易于阅读，如果您有多于一行的连续php代码，只需使用一行来启动上面的解释器第一行，最后一行之后的PHP代码。 Otherwise it tends to Fry the brain trying to read and understand the code. 否则，它会使您难以理解和理解代码。

echo '<p>sdgdfgdgd</p>';
echo '</td>';
else :
echo '<td width="2%" class="test"> </td>';
endif;
endforeach;
// if array has less than the expected 5 occ add blank columns
if ( $i < 5 ) :
$i++;
for ( $i ; $i < 5; $i++ ) :
if ( $i % 2 == 0 ) :
echo '<td width="32%" class="test">Filler</td>';

echo '</tr>';
