The new password_*methods are only available as of PHP 5.5:
新password_*方法仅从 PHP 5.5 开始可用:

Take a look at this library that provides forward compatibility:
看看这个提供向前兼容性的库:

You can use that to get access to the new password_*methods until you are able to run PHP 5.5.
您可以使用它来访问新password_*方法,直到您能够运行 PHP 5.5。
