一款简单实用的PHP以星号隐藏用户名手机号码和邮箱实例,将用户的一些文字信息隐藏一部分用星号代替,以便于保护用户隐私。
隐藏函数:
-
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:
-
<?php
-
$account = "sucaihuo.com";
-
$email = "123456789@qq.com";
-
$phone = "13800000000";
-
?>
以星号*显示实例:
-
<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>
