Php strlen（）转换为字符串

Question

如何使用strlen()根据字符串长度返回X星（*）？

<?PHP
  $account_name = "account1"; // 8 characters
  $account_name_length = strlen($account_name);

  // This is what i want to achieve - convert `$account_name` string length into stars.
  $account_name_hidden = "********"; // return 8 stars as string
?>

Answer 1

嗯，不知道你为什么要这样做，但你不能这样做吗？

<?php
$account_name = "account1" // 8 characters
$account_name_length = strlen($account_name);
$account_hidden = str_repeat('*', $account_name_length);
?>

Answer 2

以这种方式：

.subul_main li.level1 { background: #ff8400; }
