  6. // match all regular expressions
  7. preg_match_all($tag,$content,$matches);

  12. $tag_results = array();
  13. $found_tags = array();
  14. foreach ($matches as $idx => $match) {
  15. //build arg array
  16. $full_tag = array_shift($match);
  17. //call function, adding function output and full tag text to replacement array
