最近项目中遇到这个问题，自己写了一个，利用的是mb_相关的方法，比较简单方便

static function PassStart($str,$start,$end=0,$dot=”*”,$charset=”UTF-8″){

$len = mb_strlen($str,$charset);

if($start==0||$start>$len){

$start = 1;

}

if($end!=0&&$end>$len){

$end = $len-2;

}

$endStart = $len-$end;

$top = mb_substr($str, 0,$start,$charset);

$bottom = “”;

if($endStart>0){

$bottom = mb_substr($str, $endStart,$end,$charset);

}

$len = $len-mb_strlen($top,$charset);

$len = $len-mb_strlen($bottom,$charset);

$newStr = $top;

for($i=0;$i

$newStr.=$dot;

}

$newStr.=$bottom;

return $newStr;

}

直接调用即可PassStart(“”, 4,4);

输出结果：

“cardid”:”6222***********3655″,”certifId”:”4304**********1011″,”mobile”:”138****6306″,”name”:”张*”,
