本文实例讲述了php实现转换html格式为文本格式的方法。分享给大家供大家参考,具体如下:

有时候需要转换html格式的字符串为文本,但又需要保持一定的格式,比如要求段落变成的分段格式就可以用下面这个函数

function html2text($str){
 $str = preg_replace("/<style .*&#63;<\\/style>/is", "", $str);
 $str = preg_replace("/<script .*&#63;<\\/script>/is", "", $str);
 $str = preg_replace("/<br \\s*\\/>/i", ">>>>", $str);
 $str = preg_replace("/<\\/&#63;p>/i", ">>>>", $str);
 $str = preg_replace("/<\\/&#63;td>/i", "", $str);
 $str = preg_replace("/<\\/&#63;div>/i", ">>>>", $str);
 $str = preg_replace("/<\\/&#63;blockquote>/i", "", $str);
 $str = preg_replace("/<\\/&#63;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", '"', $str);
 $str = preg_replace("/&ldquo/i", '"', $str);
 $str = preg_replace("/‘/i", "'", $str);
 $str = preg_replace("/&lsquo/i", "'", $str);
 $str = preg_replace("/'/i", "'", $str);
 $str = preg_replace("/&rsquo/i", "'", $str);
 $str = preg_replace("/>/i", ">", $str);
 $str = preg_replace("/>/i", ">", $str);
 $str = preg_replace("/”/i", '"', $str);
 $str = preg_replace("/&rdquo/i", '"', $str);
 $str = strip_tags($str);
 $str = html_entity_decode($str, ENT_QUOTES, "utf-8");
 $str = preg_replace("/&#.*&#63;;/i", "", $str);
 return $str;
}
