方法一,strip_tags()剥去字符串中的 HTML 标签: - <?php
- echo strip_tags("Hello <b>world!</b>");
- //运行结果:Hello world!
- ?>
复制代码
方法二,自定义函数去除 - function cutstr_html($string, $sublen)
- {
- $string = strip_tags($string);
- $string = preg_replace ('/\n/is', '', $string);
- $string = preg_replace ('/ | /is', '', $string);
- $string = preg_replace ('/ /is', '', $string);
- preg_match_all("/[\x01-\x7f]|[\xc2-\xdf][\x80-\xbf]|\xe0[\xa0-\xbf][\x80-\xbf]|[\xe1-\xef][\x80-\xbf][\x80-\xbf]|\xf0[\x90-\xbf][\x80-\xbf][\x80-\xbf]|[\xf1-\xf7][\x80-\xbf][\x80-\xbf][\x80-\xbf]/", $string, $t_string);
- if(count($t_string[0]) - 0 > $sublen) $string = join('', array_slice($t_string[0], 0, $sublen))."…";
- else $string = join('', array_slice($t_string[0], 0, $sublen));
- return $string;
- }
