Implement a multiple column table using foreach loop - php

Question

I want to implement a logic for creating a three column table using foreach loop. A sample code will look like this.
$array = ['0','1','2','3','4','5','6'];
$table = '<table class="table"><tbody>';
foreach($array as $a=>$v){
//if 0th or 3rd???????????wht should be here?
$table .= '<tr>';
$table .= '<td>$v</td>';
//if 2nd or 5th??????????and here too???
$table .= '</tr>';
}
$table = '</tbody></table>';
Any ideas?
Expected output is a simple 3X3 table with the values from the array

Answer 1

Use this you may looking for this
<?php
echo('<table><tr>');
$i = 0;
foreach( $array as $product )
{
$i++;
echo '<td>'.$product .'</td>';
if($i % 3==0)
{
echo '</tr><tr>';
}
}
echo'</tr></table>';
?>
Result Here:
<table>
<tr>
<td>data1</td>
<td>data2</td>
<td>data3</td>
</tr>
<tr>
<td>data4</td>
<td>data5</td>
<td>data6</td>
</tr>
</table>

Answer 2

This should work for you:
(See that I added a tr at the start and end before and after the foreach loop. Also I changed the quotes to double quotes and made sure you append the text everywhere.)
<?php
$array = ['0','1','2','3','4','5','6'];
$table = "<table class='table'><tbody><tr>";
//^^^^ See here the start of the first row
foreach($array as $a => $v) {
$table .= "<td>$v</td>";
//^ ^ double quotes for the variables
if(($a+1) % 3 == 0)
$table .= "</tr><tr>";
}
$table .= "</tr></tbody></table>";
//^ ^^^^^ end the row
//| append the text and don't overwrite it at the end
echo $table;
?>
output:
<table class='table'>
<tbody>
<tr>
<td>0</td>
<td>1</td>
<td>2</td>
</tr>
<tr>
<td>3</td>
<td>4</td>
<td>5</td>
</tr>
<tr>
<td>6</td>
</tr>
</tbody>
</table>

Answer 3

Here is an easy solution with array_chunk():
<?php
$array = array('0','1','2','3','4','5','6');
$d = array_chunk($array, 3);
$table = "<table border='1' class='table'><tbody>";
foreach($d as $v)
$table .= "<tr><td>" . implode("</td><td>", $v) . "</td></tr>";
$table .= "</tbody></table>";
echo $table;
?>

Here is an easy solution with incrementing that works with a dynamically generated table like the one in Magento product view page to help display product attributes in two table columns preceded by attribute label -> practically we have 4 table columns together with attribute labels. This is useful for products with multiple attributes that take a long page to display.
<?php
$_helper = $this->helper('catalog/output');
$_product = $this->getProduct();
if($_additional = $this->getAdditionalData()): ?>
<h2><?php echo $this->__('Additional Information') ?></h2>
<table class="table table-bordered table-hover" id="product-attribute-specs-table">
<col width="25%" />
<col />
<tbody>
<?php $i = 1; ?>
<tr>
<?php foreach ($_additional as $_data): ?>
<?php $_attribute = $_product->getResource()->getAttribute($_data['code']);
if (!is_null($_product->getData($_attribute->getAttributeCode())) && ((string)$_attribute->getFrontend()->getValue($_product) != '')) { ?>
<th style="width: 20%;"><?php echo $this->htmlEscape($this->__($_data['label'])) ?></th>
<td class="data" style="width:20%;"><?php echo $_helper->productAttribute($_product, $_data['value'], $_data['code']) ?></td>
<?php $i++; if($i > 1 && ($i & 1) ) echo "</tr><tr>";?>
<?php } ?>
<?php endforeach; ?>
</tr>
</tbody>
</table>
<script type="text/javascript">decorateTable('product-attribute-specs-table')</script>
