Question

I’m trying to get a new to fire the first time in my loop and then after 4 counts close the and then open a new in my loop i tried doing this with modulus but i don’t think I am doing it correctly.

Code I tried:

<?php for($i = 1; $i <= 12; $i++): ?>
    <?php if(! (i % 4)): ?>
        <div class="row">
    <?php endif; ?>

    <?php echo $i; ?>

    <?php if(! (i % 5)): ?>
        </div>
    <?php endif; ?>
<?php endfor; ?>

So my results should be:

<div class="row">
1 2 3 4
</div>
<div class="row">
5 6 7 8
</div>
<div class="row">
9 10 11 12
</div>

etc…

Answer 1

The simplest solution would be to :

• start outputting the before marker
• then, loop over your items
  • displaying the item
  • and, if $i % 4 == 3, putting both an after and a before markers
• and, finally, display a final after marker.

For example, something like this portion of code :

$arr = range(1, 15);

echo "before";
for ($i=0 ; $i<count($arr) ; $i++) {
    echo " $i ";
    if ($i % 4 == 3) {
        echo 'after</br />';
        echo 'before';
    }
}
echo "after<br />";

Will give that kind of output :

before 0 1 2 3 after
before 4 5 6 7 after
before 8 9 10 11 after
before 12 13 14 after

Advantage of this solution : you do not have to deal with any specific case (beginning and end of the loop) inside the loop.
