Recent posts, calling a function "the_category"

I use the following code to display the recent posts.

<?php
  $args = array( 'numberposts' => '5' );
  $recent_posts = wp_get_recent_posts( $args );
  foreach( $recent_posts as $recent ){
  echo '<li>
  <a class="permalink" href="' . get_permalink($recent["ID"]) . '" title="Look '.esc_attr($recent["post_title"]).'" >' .   $recent["post_title"].'</a>
  <span class="category">Posted in ??????</span>
        </li> ';
	}
?>

how to call function “the_category” and use it instead of “??????” ?

Regards
