Strip html

Is there a way to strip all html out of an export for content? I did a search and found this snippet of code but it doesn’t appear to be working anymore.

add_filter( 'woe_fetch_order', function($rec ,$order) {
 array_walk_recursive($rec,  function(&$a) {
   $a = strip_tags($a);
 } );
 return $rec;
}, 10, 2);
