how to display wordpress categories in two columns? - php

Question

I'd like to display my categories 2 at the time - 2 in each row and have as many rows as needed.
I've got so far with this code (which displays all the categories):
<?php
$i = 1;
$args = array(
'orderby' => 'name',
'parent' => 0,
'hide_empty' => 0
);
$categories = get_categories( $args );
echo count( $categories );
echo "<div class='a'>\n";
foreach ( $categories as $category ) {
echo "<div class='b'>\n";
echo "<div class='c'><a href='" . get_category_link( $category->term_id ) . "'>" . $category->name . "</a></div>\n";
echo "</div>\n";
}
echo "</div>\n";
?>
I know it can be done using list, but this is something I want to avoid.

So this is it (took a while) and it works just fine ;-)
$args = array(
'orderby' => 'name',
'parent' => 0,
'hide_empty' => 1
);
$categories = get_categories( $args );
$list_cats = array();
foreach ( $categories as $category ) {
array_push($list_cats, $category->name);
}
$total_cats=count($categories);
echo "<div class='a'>";
for ($a=0; $a<$total_cats;) {
for ($j=0; $j<2; $j++) {
echo " <div class='b'><div class='c'>" . $list_cats[$a] . "</div></div>";
$a++;
}
echo "</div>";
if($a<$total_cats){
echo "<div class='a'>";
}
}
