我想把abcdefgh@aliyun.com转成abc**@aliyun.com 这种格式,除了使用substr处理和替换 还有没有其他高级的写法?

正则表达式

<code class="php">$pattern = "/(\\S{3})\\S*?(@\\S*)/";
$replacement = "\\1***\\2";
$str = "abcdefgh@aliyun.com"; 
 
$result = preg_replace($pattern, $replacement, $str);
echo $result;</code>

<code><?php $str="abcdefgh@aliyun.com";
echo substr_replace($str,'*****',3,5);</code></code>
