Combine Terms under same Title, unless new = create new Title Wordpress Query

Question

During a 'foreach' loop, if the same term is detected, only add the page link, otherwise add the term name and page link during a single wp_query?

So for example:

1. Title 1 Apple Pie
2. Title 1 Cherry Pie
3. Title 2 Ham Pie
4. Title 3 Goat Pie
5. Title 1 Noodle Cake

Should Become:

1. • Title 1
     • Apple Pie,
     • Cherry Pie,
     • Noodle Cake
2. • Title 2
     • Ham Pie
3. • Title 3
     • Goat Pie

Answer 1

I hope this helps.

$titles = array('Title 1 Apple Pie','Title 1 Cherry Pie','Title 2 Ham Pie','Title 3 Goat Pie');
$list = '<ol>';
foreach ($titles as $value) {
$subtitle = substr($value, 0, 7);
if(!strpos($final,$subtitle )){
   $list .= '<li>' . $value . '</li>' ;
}  else {
    $pos = stripos($list, $subtitle);
    $left_string = substr($list,0, $pos);
    $substring = substr($list, $pos);
    $next_pos = stripos($substring, '<');
    $right_string = substr($substring, $next_pos);
    $current = substr($substring, 8, $next_pos);
    $current = rtrim($current, '</li>');
    $list = '';
    $last = $current . ' '. substr($value, 8);
    $list = $left_string .' '. $subtitle.' '. $last . ' '.      $right_string;
      }
  }
    $final .= '</ol>';
     echo $final;

output.
