preg_replace'</ p>'和'<br />'？

Question

我有我的代码删除<p>起始标记,但现在我想</p>用换行符替换结束标记.我怎样才能做到这一点？

这就是我所拥有的:

$content = 'This is the content';
$newcontent = preg_replace("/<p[^>]*?>", "", $content);
$newcontent = preg_replace("</p>", "<br />", $newcontent);

Answer 1

使用str_replace而不是preg_replace,所以:

$content = '<p>This is a new content for missing slash</p>';
$newcontent = preg_replace("/<p[^>]*?>/", "", $content);
$newcontent = str_replace("</p>", "<br />", $newcontent);

Answer 2

$content = preg_replace('#<p(.*?)>(.*?)</p>#is', '$2<br/>', $content);
