thinkphp模板截取中⽂（限制显⽰字数）把如下代码粘贴到thinkphp核⼼包的/common/functions.php 的最后便可在html模型⾥直接使⽤
//函数解释：
puss in boots
//msubstr($str, $start=0, $length, $chart=”utf-8″, $suffix=true)famine>companion
//$str：要截取的字符串
// $start=0：开始位置，默认从0开始
// $length：截取长度

tuoci// $chart=”utf-8″：字符编码，默认UTF－8
禽流感症状h7n9症状
// $suffix=true：是否在截取后的字符后⾯显⽰省略号，默认true显⽰，fal为不显⽰
