方法一,strip_tags()剥去字符串中的 HTML 标签:
1 2 3 4 | <?php echo strip_tags("Hello <b>world!</b>"); //运行结果:Hello world! ?> |
方法二,自定义函数去除
1 2 3 4 5 6 7 8 9 10 | 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; } |
