PHP：用正则表达式从简介中删除锚和其他标记

Posted 2021-02-26

"Recently I was playing around with WordPress’ wp_posts table. I wanted to grab the basic information about my posts (ID, title, content, slug) and build a quick summary list of them. One problem I ran into was creating a content “intro.” Luckily a quick regular expression allowed me to create the intro."

preg_match("/<p>(.*)</p>/",$post['post_content'],$matches);
$intro = strip_tags($matches[1]); //removes anchors and other tags from the intro
