I have the script below and I need to return both of the conditional return values -- each result on a line. Is there any way to format it as an array in order to work ?
The script is:
if ($pdf_url != '') {
    if ($title != '') {
        $title_from_url = $this->make_title_from_url($pdf_url);
        if ($title == $title_from_url || $this->make_title_from_url('/'.$title) == $title_from_url) {
            // This would be the default title anyway based on URL
            // OR if you take .pdf off title it would match, so that's close enough - don't load up shortcode with title param
            $title = '';
        } else {
            $title = ' title="' . esc_attr( $title ) . '"';
        }
    }
    return apply_filters('pdfemb_override_send_to_editor', '[pdf-embedder url="' . $pdf_url . '"'.$title.']', $html, $id, $attachment);
} else {
    return $html;
}
