mb_substr中文日文长度相同,显示长度不同
两段中文和日本,从肉眼上看是不在同一位置结束的,但是使用mb_strlen函数获取的长度确是相同的,测试代码如下:
<code>$str_0 = '[银光字幕组][哆啦A梦新番Doraemon][006][GB][2005.05.20]秘密间谍大作战&Hello!宇'; $str_1 = 'Hello Kitty no Happy Birthday (ハローキティとミミィのハッピーバースデー) OVA.mp'; $str_2 = 'ARR] Hello Kitty no Fushigi no Kuni no Alice (ハローキティの不思議の国の'; $str_3 = '2014.myHD.六福喜事.Hello Babies.粵語中字.AC-3.1920x1080-MYfun4U.mkv'; return mb_strlen($str_0, 'utf-8').'@'.mb_strlen($str_1, 'utf-8').'@'.mb_strlen($str_2, 'utf-8').'@'.mb_strlen($str_3, 'utf-8'); </code>
测试结果长度都是59,但是肉眼很明显看到长度不统一啦,这样的话就会造成mb_substr这个函数截取的数据长度不统一,在前端就会换行了。
大家是如何解决这个问题的?

...我这里程序输出的是59...然后我每个都特地数了两遍..都是59个字..mb_strlen
并没有问题...
