Display categories that start with a certain letter

    Hey guys,
    I’m trying to display categories that are grouped by the letter they start with. Eg

    A
    Apples,
    Apricots
    Anjas
    B
    Bananas
    Beats
    C
    etc etc

    I really don’t want to create sub-categories under each letter. Instead, I’d prefer to do this programmatically if possible. My problem is that I’m a complete nubie to php!

    The code below by gcarson shows how to do it perfectly for tags. However, I can’t (for the life of me) figure out how to do the same thing with categories. Can anyone help? Any advice would be much appreciated.

    <?php
$tags = get_tags( array('name__like' => "a", 'order' => 'ASC') );
$tags_count = count($tags);
$count = intval( $tags->count );
$percolumn = ceil($tags_count / 3);

for ($i = 0;$i < $tags_count;$i++):
    if ($i < $percolumn):
    $tag_left .= '
	<li><a href="'. get_tag_link($tags[$i]->term_id) . '"rel="tag">' . $tags[$i]->name .' (' . $tags[$i]->count . ')</a></li>
' . "\n";
    elseif ($i >= $percolumn && $i < $percolumn*2):
    $tag_mid .= '
	<li><a href="'. get_tag_link($tags[$i]->term_id) . '"rel="tag">' . $tags[$i]->name .'  (' . $tags[$i]->count . ')</a></li>
' . "\n";
    elseif ($i >= $percolumn*2):
    $tag_right .= '
	<li><a href="'. get_tag_link($tags[$i]->term_id) . '"rel="tag">' . $tags[$i]->name .' (' . $tags[$i]->count . ')</a></li>
' . "\n";
    endif;
endfor;
?>

<div class="list">
<ul>
<?php echo $tag_left; ?>
</ul>
</div>

<div class="listlist">
<ul>
<?php echo $tag_mid; ?>
</ul>
</div>

<div class="list">
<ul>
<?php echo $tag_right; ?>
</ul>
</div>

    For reference, this is the post the code came from: http://wordpress.org/support/topic/a-z-index-list-of-tags

    Thanks vtxyzzy! Thats a really useful bit of code!

    For anyone who is interested, I’ve also (finally) figured out how to make the original code suitable for categories;

    These are categories starting with b
				<?php
				$args = array('name__like' => "b", 'order' => 'ASC');
				$categories = get_terms( 'category', $args );
				$categories_count = count($categories);
				$count = intval( $categories->count );
				$percolumn = ceil($categories_count / 3);

				for ($i = 0;$i < $categories_count;$i++):
					if ($i < $percolumn):
					$category_left .= '
					<li><a href="'. get_category_link($categories[$i]->term_id) . '">' . $categories[$i]->name .' (' . $categories[$i]->count . ')</a></li>
				' . "\n";
					elseif ($i >= $percolumn && $i < $percolumn*2):
					$category_mid .= '
					<li><a href="'. get_category_link($categories[$i]->term_id) . '">' . $categories[$i]->name .'  (' . $categories[$i]->count . ')</a></li>
				' . "\n";
					elseif ($i >= $percolumn*2):
					$category_right .= '
					<li><a href="'. get_category_link($categories[$i]->term_id) . '">' . $categories[$i]->name .' (' . $categories[$i]->count . ')</a></li>
				' . "\n";
					endif;
				endfor;
				?>

				<div class="list">
				<ul>
				<?php echo $category_left; ?>
				</ul>
				</div>

				<div class="listlist">
				<ul>
				<?php echo $category_mid; ?>
				</ul>
				</div>

				<div class="list">
				<ul>
				<?php echo $category_right; ?>
				</ul>
				</div>
