在自己项目用到的哈，英文和中文往往字数不一样。用到多语言的项目记得收藏哦！~完全原创~function msubstr($str, $start = 0, $length, $lenth2, $suffix = true) {<br>
//$length 中文截取长度，$lenth2英文截取长度 $suffix 是否省略号<br>
$charset = 'utf-8';<br>
if (LANG_SET != 'zh') {<br>
$length = $lenth2;<br>
}<br>
$str = preg_replace("/(\|\r|\n|\s|\[.+?\])/is", ' ', $str);<br>
