php怎么过滤掉智能ABC打出来的V11
就是空格,这个空格识别不了,ctype_space和preg_replace('/\s\s+/','',$nick)==''都不行,就是全部是那种空白不允许写入数据库。
回复讨论(解决方案)
只能ABC v11 打出来的是全角空格
只能ABC v11 打出来的是全角空格
哦,就是说无法用正则过滤,只能用replace强行过滤是吗
$nick = preg_replace('/\s| /', '', $nick);
$nick = preg_replace('/\s| /', '', $nick);
可以,测试通过,大侠你是不是手动在后面用智能abc打了个v11?
$nick = preg_replace('/\s| /', '', $nick);
是打了智能abc的v11进去正则的。
$a = ' ';$b = ' ';echo base64_encode($a).'<br>'; // 44CAecho base64_encode($b); // IA==
嗯,很巧妙的解决方法,完美解决了我的难题,谢谢
