function html2text($str){
 $str = preg_replace("/<style .*?<\\/style>/is", "", $str);
 $str = preg_replace("/<script .*?<\\/script>/is", "", $str);
 $str = preg_replace("/<br \\s*\\/>/i", ">>>>", $str);
 $str = preg_replace("/<\\/?p>/i", ">>>>", $str);
 $str = preg_replace("/<\\/?td>/i", "", $str);
 $str = preg_replace("/<\\/?div>/i", ">>>>", $str);
 $str = preg_replace("/<\\/?blockquote>/i", "", $str);
 $str = preg_replace("/<\\/?li>/i", ">>>>", $str);
 $str = preg_replace("/ /i", " ", $str);
 $str = preg_replace("/ /i", " ", $str);
 $str = preg_replace("/&/i", "&", $str);
 $str = preg_replace("/&/i", "&", $str);
 $str = preg_replace("/</i", "<", $str);
 $str = preg_replace("/</i", "<", $str);
 $str = preg_replace("/“/i", &#39;"&#39;, $str);
 $str = preg_replace("/&ldquo/i", &#39;"&#39;, $str);
 $str = preg_replace("/‘/i", "&#39;", $str);
 $str = preg_replace("/&lsquo/i", "&#39;", $str);
 $str = preg_replace("/&#39;/i", "&#39;", $str);
 $str = preg_replace("/&rsquo/i", "&#39;", $str);
 $str = preg_replace("/>/i", ">", $str);
 $str = preg_replace("/>/i", ">", $str);
 $str = preg_replace("/”/i", &#39;"&#39;, $str);
