Split PHP loop into 2 lists - php

Question

I have built the following function, but is it possible to get it to split my lists from one into more so I can have a maximum of 8 <li>'s per <ul>?
function buildProductsMenu($base) {
$sql = "SELECT *
FROM tbl_category";
$result = dbQuery($sql);
while ($row = dbFetchAssoc($result)) {
echo "<ul>";
echo "<li class='title'>$row[cat_name]</li>";
$sqlProd = "SELECT *
FROM tbl_product WHERE cat_id = $row[cat_id]";
$resultProd = dbQuery($sqlProd);
while ($rowProd = dbFetchAssoc($resultProd)) {
extract($rowProd);
echo "<li><a href='".$base."products/".strtolower($row['cat_name'])."/".strtolower($pd_name)."'>".$pd_name."</a></li>";
}
echo "</ul>";
}
}

$resultProd = dbQuery($sqlProd);
$counter = 1;
while ($rowProd = dbFetchAssoc($resultProd)) {
extract($rowProd);
if($counter % 12 == 0) {
$counter = 1;
echo "</ul><ul style='margin-top:25px;'>";
}
echo "<li><a href='".$base."products/".strtolower($row['cat_name'])."/".strtolower($pd_name)."'>".$pd_name."</a></li>";
$counter++;
}
echo "</ul>";
}
}

Answer 1

You can add a counter, and when that counter reaches 8, you start a new ul.
$counter = 1;
while ($rowProd = dbFetchAssoc($resultProd)) {
extract($rowProd);
if($counter % 8 == 0) {
$counter = 1;
echo "</ul><ul>";
}
echo "<li><a href='".$base."products/".strtolower($row['cat_name'])."/".strtolower($pd_name)."'>".$pd_name."</a></li>";
counter++;
}

Okay, instead of echoing the LIs right from the function I suggest you add them all to an array, once things are in an array, its always easier to manage.
Use array_chunk() on the final array of LIs and it will split it into groups of eight.
