Can wp_list_comments output into variable?

2 comments

1. In the default usage this is impossible due to the nature of the default comment walker which always directly outputs. But the function allows to provide a custom walker.

   Further reading about custom walkers:
   Codex Class reference
   example custom walker class

   You could also use output buffering to save it into a variable (this is considered to be dirty):

   ob_start();
   wp_list_comments(array('reverse_top_level' => false ), $comments);
   $variable = ob_get_clean();
   

2. According to Function Reference for wp_list_comments, you can set the arg Echo to false to return the list.

   I imagine the default walker will not echo the code if this is set to false.

   wp_list_comments(array('reverse_top_level' => false, 'echo' => false), $comments);
