Problem with a table while coding on PHP

[Jacek]

I want to make a display of three cell lines. But the second line does not jump after three cells? Here is my code:

PHP Code:

<table> 
<tr style="margin:20px; border:1px solid red; padding: 20px;"> 
<?php 
$j = 1; 
foreach ($result as $row) 
{ 
$id = $row ['id']; 
$image = $row ['image']; 
$name = $row ['name']; 
$price = $row ['price']; 
$description = $row ['description']; 
stockMinimum $ = $row ['stockMinimum'];?> 
<td style = "border: 1px solid # fff; padding: 0px; position: relative; background-color: transparent; margin: 0px; text-align: center; width: 250px" > 
<h3 style="text-align:left; font-size:90%; margin:0 0 0 10px; padding:0;" > 
<?php echo nl2br ($ model-> debutTexte ($ name, 18 ));? > 
</h3> 
<span style="font-weight: bold; margin:0 0 0 110px;" > 
<?php echo $ price;?> &nbsp;&euro;
</span> 
<p> <?php 
$tabImage = explode ( '', $ image); 
if (isset ($tabImage [0]) &&! empty ($tabImage [0])) 
{
echo ' 
<a href = "?page=detailProduct&amp; idProduct = '.$id.'&amp; category = '.$idCategory.'" >

<img src = "http://forums.techarena.in/images/'.$tabImage[0]." 
style = "border: 3px solid # fff; height: 140px; width: 140px;" alt = "product $tabImage[0]" /> 
</a>'; 
} 
else 
echo '<img src="img/noImage.jpg" style="height:90px; width:90px;" alt="Aucune image description" />';?
</p> 
<p> 
<span style="display:block;"> 
<?php echo html_entity_decode (nl2br ($model -> debutTexte ($description,17)));?> 
</span> 
<span style="display:block;"> 
<a href="?page=detailProduct&amp; idProduct=<?php echo $id;?>&amp; category=<?php echo $idCategory;?>">
see description 
</a> 
</span> 
</p> 
</td> <?php 
if ($ j%6 == 3) echo '</ tr><tr>'; 
$ j++; 
} 
}?> 
</tr></table>

I don't know much about PHP but in my opinion there should be some problem in the below code:

PHP Code:

if ($ j%6 == 3) echo '</tr><tr>;  
$ j++;

Yes Baltazar, you are right. It should be

PHP Code:

if ($ j% 3 == 0) echo '</tr> <tr>'; 
$ j++; 


With your below code:

PHP Code:

if ($ j% 6 == 3) echo '</ tr> <tr>'; 


j = 1, 2 and 3: 3% 6 ==> 3 / 6 = 0 remainder 3. So it works.
But j = 6: 6% 6 ==> 6 / 6 = 1 is 0, it does more. Therefore, when on the second line, it does not jumps.

It is useless to have % 6 while you want a % 3!

[Jacek]

Thanks for your responses. But I am confused between j%3 == 0 and j/3 = 0? Are they one and the same?

[BiGMaCHiNe]

The mod returns the below result:

1 % 3 = 1 - (3 * 0) = 1
2 % 3 = 2 - (3 * 0) = 2
3 % 3 = 3 - (3 * 1) = 0
4 % 3 = 4 - (3 * 1) = 1
5 % 3 = 5 - (3 * 1) = 2
6 % 3 = 6 - (3 * 2) = 0

Therefore, test $ j % 3 == 0 => 3 equals 0 <=> $ j is a multiple of 3.
