Question

I am trying to get the last entry in a foreach loop but struggling so far. My biggest problem is that once inside the foreach loop, I need to filter the array by eliminating every author who has 0 posts. This is my code so far:

$authors = get_users('orderby=nicename');


foreach ($authors as $author ) {
      if ( count_user_posts( $author->id ) >= 1 ) { IF LAST {special <li>} else {normal <li> }

Can anyone shed some light on how to get the last entry in this scenario? Thanks

You should write a function to filter the array and then you can pop the last item off of it like this:

// use this section of code in PHP >= 5.3 - utilizes anonymous function
$filtered_array = array_filter($authors, function($author) {
    if(count_user_posts($author->id) >= 1) return true;
    return false;
});

// use this section of code for older versions of PHP - uses regular function
function author_filter($author) {
    if(count_user_posts($author->id) >= 1) return true;
    return false;
}
$filtered_array = array_filter($authors, 'author_filter');

// the rest is the same regardless of PHP version
$last_author = array_pop($filtered_array);

// output
foreach($filtered_array as $author) {
    // regular output
}
// then do special output for $last_author
