数组键值替换 php

用到的php函数   substr_replace(string,replacement,start,length)  strlen();

实现功能  根据用户的权限 银行卡隐藏中间12位数字

$admin = array("超级管理员","财务经理","财务查询");
$admin_name = $_G['user_result']['typename']; //检测当前管理员用户名

if( !in_array($admin_name,$admin) ){
foreach( $result['list'] as $key => $value ){
$acc_result = $value['account'];
if($acc_result==""){
$acc_sub = "";
}else if(strlen($acc_result)== 16 ){
$acc_sub = substr_replace($acc_result,"*********",4,8);
}else{
$acc_sub = substr_replace($acc_result,"************",4,11);
}
$result['list'][$key]['account'] = $acc_sub;

}

}
