如何隐藏邮件地址

Question

我有一个表，显示一些数据钱包地址或电子邮件。

我需要什么时候是电子邮件，然后隐藏字母@像这样****@gmail.com

我的表在前端php是:

<table class="table table-striped text-center"><thead><tr>
<th scope="col">Username</th>
<th scope="col">Address</th>
</tr>
</thead>
<tbody>
<?php
foreach ($withdrawHistory as $wd) {
echo '<tr><td>' . $wd["username"] . '</td>
<td>' . $wd["wallet"] . '</td>
</tr>'; }?> </tbody></table>

有办法隐藏吗?

<?php
foreach ($withdrawHistory as $wd) {

Answer 2

一种方法是使用explosion(在foreach循环中)，然后只返回$email。

$wallet = explode("@", $wd["wallet"]);
$email = "****@". $wallet[1];
echo $email;

如果你想要@前面的字母个数匹配*的个数，使用这个

$wallet = explode("@", $wd["wallet"]);
$y = strlen($wallet[0]);
$hidden = "";
for ($x = 1; $x <= $y; $x++) {
$hidden .= "*";
}
$email = $hidden ."@". $wallet[1];
echo $email;
