注释
WarningNote:
mb_regex_encoding() 指定的内部编码或字符编码将会当作此函数用的字符编码。
处理非信任的输入时从不使用 e 修饰符,就不会转码(即调用 preg_replace())。不注意 这些会很可能会导致应用程序引发远程代码执行的漏洞。
Never use the e modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace()). Not taking care of this will most likely create remote code execution vulnerabilities in your application.
