    I am using this code to not display a specific category name in the category list:

    <?php
                              foreach((get_the_category()) as $category) {
                                 if ($category->cat_name != 'Featured') {
                                    echo '<a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> ';
                                 }
                              }
                           ?>

    I need to know how to add a comma after each category name but not on the last category that is listed. Any thoughts?

    possibility A:

    <?php $cats = array();
                              foreach((get_the_category()) as $category) {
                                 if ($category->cat_name != 'Featured') {
                                    $cats[] = '<a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> ';
                                 }
                              }
  echo implode(', ', $cats);                         ?>

    possibility B:

    <?php $separator = '';
                              foreach((get_the_category()) as $category) {
                                 if ($category->cat_name != 'Featured') {
                                    echo $separator . '<a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> ';
$separator = ', ';
                                 }
                              }
                           ?>

    Thank-you. Both of those worked. I had to remove the space after the closing of the anchor tag so that the comma was directly after the name of the category and didn’t have a space before and after them. Thank-you for your help!
