Get & Store category info

I’m wondering: is there any way I can load all the categories and store each one in a different array?

So i’ve got this code:

<?php $cat_args=array('orderby' => 'name','order' => 'ASC');
$categories=get_categories($cat_args);
foreach($categories as $category) {
$args=array(
  'showposts' => -1,
  'category__in' => array($category->term_id),
  'caller_get_posts'=>1
);
$posts=get_posts($args);
  if ($posts) {
    echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
    foreach($posts as $post) {
      setup_postdata($post); ?>
      <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
      <?php
    } // foreach($posts
  } // if ($posts
} // foreach($categories

I want to make it so that I can use it later like that (outside the loop):
<?php echo $category[0] -> name . $category[1] -> name . $category[2] -> name; ?>

How can I do that?
