I'm writing a function which requires some units of date, like "hour", "minute" and "second" but I would like to make these option and the server's current time is used as the default. In PHP's mktime(..) I notice that they use function calls to get the default argument value - but when I try this, it doesn't work: PHP's appears to be like thi
我正在写一个函数，它需要一些日期单位，如“小时”，“分钟”和“秒”，但我想做出这些选择，并将服务器的当前时间用作默认值。 在PHP的mktime(..)我注意到他们使用函数调用来获取默认参数值 - 但是当我尝试这个，它不起作用： PHP的似乎是这样的： mktime([int $hour = date("H")[,int $minute= date("i")[,etc... 我已经尝试将它复制到我的函数中，完全相同（只是没有很多参数，直到我得到它的工作）： f
I would like to do something like this: function readUser($aUser = loadDefaultUser()){ //doing read User } I find that it will display a error to me, how can I pass a function return as a default value? Thank you. Yes, you can provide a default argument. However, the default argument "must be a constant expression, not (for example) a variable, a class member or a function call."
我想要做这样的事情： function readUser($aUser = loadDefaultUser()){ //doing read User } 我发现它会向我显示一个错误，我如何将函数返回值作为默认值传递？ 谢谢。 是的，您可以提供默认参数。 但是，默认参数“必须是常量表达式，而不是（例如）变量，类成员或函数调用”。 您可以通过对默认值使用某个常量值来伪造此行为，然后在调用该函数时将其替换为函数调用的结果。 我们将使用NULL ，因为这是一个非常典型
