推荐答案

新的password_*方法仅在PHP 5.5及更高版本中可用:

The new password_* methods are only available as of PHP 5.5:

http://www.php.net/manual/en/function.password-hash .php

看看这个提供前向兼容性的库:

Take a look at this library that provides forward compatibility:

https://github.com/ircmaxell/password_compat

您可以使用它来访问新的password_*方法，直到能够运行PHP 5.5.

You can use that to get access to the new password_* methods until you are able to run PHP 5.5.
