Question

I would need your help with a looping issue, it’s so annoying when the brain just stop functioning.

This is what I want to do:

1. I’ve got an array with some amount of data in it, lets say [6] in this case

2. From the length of this array I create a certain amount of divs. Each div will hold a maximum of 5 array values. So number of divs that will be created = round(sizeof array/5), so 2 divs in this case.

So far so good, but now to the part I can’t figure out. How do I create the loop that prints out index 0-4 in div 1 and then goes forward and creates a second div to print out index 5-6 in.

And of course it should all be dynamically so if I’ve got 20 values in the array it will create and fill 4 divs with the values.

Thanks in advance!

Edit: Thanks everybody for your solutions!

Warning: Untested code. Try this, though.

$perRow = 4;
$myContentArray = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
$total = count($myContentArray);
$maxDivs = 3;

for($i = 0, $c = 0; $i < $total && $c <= $maxDivs; $i += $perRow + 1, $c++)
{
    echo '<div>';
    for($j = $i; $j <= $i + $perRow && $j < $total; $j++)
    {
        echo $myContentArray[$j] . ' ';
    }
    echo '</div>';
}

This prints out:

<div>1 2 3 4 5 </div><div>6 7 8 9 10 </div>
