List authors by posts?

Don’t know how efficient this is:

<?php
//Get users and count of posts put into array $uc, sort array by post count descending, loop through array and echo user info
$uc=array();
$blogusers = get_users_of_blog();
if ($blogusers) {
  foreach ($blogusers as $bloguser) {
    $post_count = get_usernumposts($bloguser->user_id);
    $uc[$bloguser->user_id]=$post_count;
  }
  arsort($uc); //use asort($uc) if ascending by post count is desired
  foreach ($uc as $key => $value) {
    $user = get_userdata($key);
    $author_posts_url = get_author_posts_url($key);
    $post_count = $value;
    echo 'User ID ' . $user->ID . ' ' . $user->user_firstname . ' ' . $user->user_lastname . ' number of posts:' . $post_count . ' author posts url:' . $author_posts_url .'';
  }
}
?>

[Edit – note that it is descending using arsort]

MichaelH you’re a life saver!! The code above works GREAT!! I’ve been searching for a way to do this for hours. Have you figured out by any chance if the code is efficient? Are there many db queries taking place? (I have no idea, just asking). Again, many thanks.

igneous, give it another try. Just copy paste it into your code and then change the echo line to show the user info! You can use this list to get the user information (name, url, etc) you need.

Looks ok to me..
