sanitize_user( string $username, bool $strict = false )
清理用户名,去掉不安全的字符。
Sanitizes a username, stripping out unsafe characters.
目录锚点:#说明#参数#源码#笔记
删除标记、八位字节、实体,如果启用了strict,则只保留字母数字、u、空格、.、-、@。清理后,它将用户名、原始用户名(参数中的用户名)和$strict值作为“sanitize_user”过滤器的参数。
参数 | 类型 | 说明 |
$username |
(string) |
要清除的用户名。 |
$strict |
(bool) |
如果设置,则将$username限制为特定字符。 |

* alphanumeric, _, space, ., -, @. After sanitizing, it passes the username,

* parameters for the 'sanitize_user' filter.
*
* @since 2.0.0
*
* @param string $username The username to be sanitized.
* @param bool $strict If set limits $username to specific characters. Default false.
* @return string The sanitized username, after passing through filters.
