本文以淘宝评论购买记录中的隐藏部分用户名作为示例，并且拓展了隐藏手机号的中间四位数，和截取邮箱部分字符串，只要输入账号，可自动识别类型并以*显示。

php中的隐藏函数：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
function hideStar($str) { //用户名、邮箱、手机账号中间字符串以*隐藏 if (strpos($str, '@')) { $email_array = explode("@", $str); $prevfix = (strlen($email_array[0]) < 4) ? "" : substr($str, 0, 3); //邮箱前缀 $count = 0; $str = preg_replace('/([\d\w+_-]{0,100})@/', '***@', $str, -1, $count); $rs = $prevfix . $str; } else { $pattern = '/(1[3458]{1}[0-9])[0-9]{4}([0-9]{4})/i'; if (preg_match($pattern, $str)) { $rs = preg_replace($pattern, '$1****$2', $str); // substr_replace($name,'****',3,4); } else { $rs = substr($str, 0, 3) . "***" . substr($str, -1); } } return $rs; } |
测试数据：
|
1 2 3 4 5 |
<?php $account = "sucaihuo.com"; $email = "416148489@qq.com"; $phone = "18005152525"; ?> |
以星号显示的示例：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
<table width="100%"> <tr> <td>账号</td> <td>邮箱</td> <td>手机</td> </tr> <tr> <td><?php echo $account;?></td> <td><?php echo $email;?></td> <td><?php echo $phone;?></td> </tr> <tr> <td><?php echo hideStar($account);?></td> <td><?php echo hideStar($email);?></td> <td><?php echo hideStar($phone);?></td> </tr> </table> |
