PHP截断函数mb_substr()详细介绍
在php中mb_substr()函数是用来截中文与英文的函数,可以方便快速的解决截取指定字符长度的问题,下面我来给大家介绍介绍。
提示:mb_substr在于php中是默认不被支持的我们需要在在windows目录下找到php.ini打开编辑,搜索mbstring.dll,找到;extension=php_mbstring.dll把前面的;号去掉才可以使用mb_substr函数哦。
Function: mb_substr( $str, $start, $length, $encoding )
$str,需要截断的字符串
$start,截断开始处
$length,长度(注意,这个跟mb_strimwidth不同,1就代表一个中文字符)
$encoding,编码,我设为 utf-8
例:截断文章标题,控制在15个文字
代码如下 | 复制代码 |
echo "mb_substr:" . mb_substr($str, 0, 7, 'utf-8'); echo "mb_strcut:" . mb_strcut($str, 0, 6, 'utf-8'); |
总结出现来他是可以解决截取中文汉字哦
