Resolved Dynamic closing div placement

[HDRebel88]

I need some help adding a closing <div> tag to my php. I want the closing tag to placed when a row of items is either 4 items long or less. So say I have two rows, one with 4 entries and one with 3... The row with 4 should add the closing div after the 4th entry, and the one with 3 should add the closing div after the 3rd (or draw a blank 4th div; which may be a better option).


Here's what I have so far:

PHP Code:

$i=0;
    foreach(glob('./images/stills/story_boards/*.*') as $filename){
    if($i==0){
    $content2.='<div>';
    }
    //$content2.='<img src="'.$filename.'" />';
    $i++;
    if($i==5){
    $i=0;
    }
    }
$content2.='</div>';

Presumably it will open after the 4 right?
Use a modulus operator.

PHP Code:

$i = 0;
$content2 = '<div>';
foreach (...)
{
    if ($i > 0 && $i % 4 == 0)
    {
        $content2 .= '</div><div>';
    }
    // append stuff here.
    ++$i;
}
$content2 .= '</div>';

That seems like it would work, but how would I get the data into the first div?

Shouldn't it be something like this:

PHP Code:

$i = 0;
$content2 = '<div>';
foreach (...)
{
    if($i==0){
    //first div's data here
    $content2.='</div><div>';
    }
    elseif ($i > 0 && $i % 4 == 0)
    {
        $content2 .= '</div><div>';
    }
    // append stuff here.
    ++$i;
}
$content2 .= '</div>';

Nope, it won't close/open the div unless you are on iteration > 0. Place whatever you want to append to $content2 where I commented it.

Edit:
For a quick example:

PHP Code:

<?php

$i = 0;
$range = range(1, 11);
$content2 .= '<div>';
foreach ($range AS $item)
{
    if ($i > 0 && $i % 4 == 0)
    {
        $content2 = rtrim($content2, ', ');
        $content2 .= '</div><div>';
    }

    $content2 .= $item . ', ';
    ++$i;
}
$content2 = rtrim($content2, ', ');
$content2 .= '</div>';
print $content2;

Should result in:

<div>1, 2, 3, 4</div><div>5, 6, 7, 8</div><div>9, 10, 11</div>

Right... it finally clicked just a second ago.

Thanks.
