Need to create two groups of items in foreach loop based on the number of items, but with a twist

Question

OK,

so I have a foreach loop in PHP.

$i = 0

$c = count($cars);

foreach ( $cars as $car ) {

   // if less than 10 items
   if ( $c < 10 ) {
      echo '<div class="column-full-width">';
         echo $i . '. ' . $car->name;
      echo '</div>';
      $i++;
   }
   // if 10 items or more
   if ( $c > 10 ) {
      if ( $c <= 5 ) {
         echo '<div class="column-left">';
            echo $i . '. ' . $car->name;
         echo '</div>';
         $i++;
      }
      if ( $c > 5 ) {
         echo '<div class="column-right">';
            echo $i . '. ' . $car->name;
         echo '</div>';
         $i++;
      }
   }

}

And I need to create 2 columns if the items in the array are 10 or more (if the are 9 max, 1 column is ok), however, the columns should be dynamically even in numbers of items that they contain... I mean if I have 10 items both columns will contain 5 items, if I have 11 items the left column will have 6 items and the right will have 5 items, if I will have 12 items both will have 6 items, if I will have 13 items, the left will have 7 and the right column will have 6 items.

How to do such condition in PHP?

What about this:

$c = count($cars);

$i = 0;

if ($c < 10) {
  echo '<div class="column-full-width">';
  foreach ($cars as $car) {
     echo ($i++) . '. ' . $car->name . '<br />';
  }
  echo '</div>';
} else {
  $lc = ceil($c / 2);     
  $act = reset($cars);   

  echo '<div class="column-left">';
  while ($i < $lc) {
    echo ($i++) . '. ' . $act->name . '<br />';    
    $act = next($cars);
  }       
  echo '</div>';     

  echo '<div class="column-right">';
  while ($i < $c) {
    echo ($i++) . '. ' . $act->name . '<br />';    
    $act = next($cars);
  }   
  echo '</div>';
}
