本文实例讲述了PHP使用正则表达式获取微博中的话题和对象名的方法。分享给大家供大家参考。具体实现方法如下:
$post_content = "@jb51和@twitter在研究用#PHP#的#正则表达式#过滤话题和对象名"; $tag_pattern = "/\#([^\#|.]+)\#/"; preg_match_all($tag_pattern, $post_content, $tagsarr); $tags = implode(',',$tagsarr[1]); $user_pattern = "/\@([a-zA-z0-9_]+)/"; $post_content = preg_replace($user_pattern, '<a href="http://twitter.com/${1}">@${1}</a>', $post_content ); $post_content = preg_replace($tag_pattern, '<a href="http://twitter.com/search?q=#${1}">#${1}#</a>', $post_content);
希望本文所述对大家的php程序设计有所帮助。
