for the first 5 rows i made this:

Answer 1

Using array_chunk()

By using array_chunk() you can generate a multi-dimensional array, with 5 elements in each.

$cars = array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J");
$carsGrouped = array_chunk($cars, 5);
foreach($carsGrouped as $carGroup){
 echo "<div class='col-lg-2'><ul>";
 foreach($carGroup as $car) {
    echo "<li>{$car}</li>";
 }
 echo "</ul></div>";
}

Using Modulus

By using the modulus operator ( % ) you can check if your counter ( $i ) is divisible by 5 , and if it is, then end the current <div> and start a new <div class='col-lg-2'> .

$cars = array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J");
echo '<div class=\'col-lg-2\'>
        <ul>';
$i = 0;
foreach($cars as $car){
    ++$i;
    echo '<li>'. $car .'</li>';
    if($i>1 AND ($i%5)===0 AND $i<count($cars)) { //We've printed 5 $car, we need to do another "group".
        echo '</ul>
           </div>
           <div class=\'col-lg-2\'>
               <ul>';
    }
} 

echo '</ul>
  </div>';

Answer 2

Using the modulus division operator as suggested, here is a possible solution;

$cars       = array("A", "B", "C", "D", "E", "F", "G", "H", "I", "s", "ee");
$iCount     = 0;
$sOutput    = '';

foreach($cars as $sCarName){

    if ($iCount % 5 == 0)
       $sOutput .= ($iCount > 1 ? "</ul>\n</div>\n" : '')."<div class='col-lg-2'>\n<ul>\n";

    $sOutput .= "<li>".$sCarName."</li>\n";

    $iCount ++;
}

if( $iCount > 1 ){
    $sOutput .= "</ul>\n</div>";  
} 

echo $sOutput;

NB its not valid html to have a div as a child of an UL , explained here

Answer 3

<?php
$cars = array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J");
?>
<div class='col-lg-2'><ul>
<?php 
$i=0;
foreach($cars as $car_name){
echo "<li>$car_name</li>";
$i++;
if($i==5): 
    echo "</ul></div><div class='col-lg-2'><ul>";
    $i = 0;
endif;
} 
?>
</ul></div>
