Need to check for duplicates before adding to search array

  • Ran into problem where a duplicate image tag is found in content and str_replace will replace the <noscript> content with lazy load image when processing duplicates. Not obvious until a page with hundreds of duplicate image tag grew very large with <noscript> tag content.

    Fix by checking for search string before adding to array:

    if (!in_array($imgHTML,$search)) {
  array_push($search, $imgHTML);
  array_push($replace, $replaceHTML);
}
