Question

I want to make it so that every 3 columns it forms a new row. I am lost and can’t figure out how to do this even after reading other posts.So I’d want it to be like

icon icon icon

icon icon icon

icon icon icon

etc….

foreach($sMenu as $row) {
    $sClass = ($row['id'] == $aPage['id']) ? ' class="ui-btn-active ui-btn-custom"' : ' class="ui-btn-custom"';
    $sIcon = ($row['icon'] != '') ? ' data-icon="' . $row['icon'] . '"' : '';

    $sSiteRoot = get('site-root');

    $row['url'] .= ($row['url'] == '') ? '' : '/';

    $url = $sSiteRoot . $row['url'];
    $url = str_replace('(', '%28', $url);
    $url = str_replace(')', '%29', $url);
    $url = str_replace("'", '%27', $url);
    $sNavigation2 .= '<td><img src=". $sIcon .' . $url . '"></td>';
}

Sometimes the easiest way to do this is to have a variable keep track of how many times you run this loop. For example:

$i = 0;

Then, inside of the loop, just check to see if the number $i is equal to 2 (in this case.)

foreach($sMenu as $row) {

    // this is all your old code right here...

    if ($i == 2) { 
        // then add your </tr><tr> break or whatever...
        $i = 0;
    } else {
        $i++;
    }
}

Then, just keep going through the foreach loop.

This can also be done using the modulus operator as a cleaner way to write this “row break” check (as shown by the other answers here.)
