问题描述

php是否支持运算符重载?

Does php support operator overloading?

我正在尝试创建一个带有日期的类，并且希望将其与另一个对象进行比较，而不必使用方法或属性.

I'm trying to create a class that takes in a date and I'd like to compare it with another object without having to use methods or properties.

这就是我想要做的:

$obj1 = new myClass('2016-08-15');
$obj2 = new myClass('2016-02-06');

if ($obj1 > $obj2){
    ...
}

我知道如何进行日期比较，我只需要知道如何使运算符超载>，<和==.

I know how to do the date comparison, all I need to know is how to overload the operators >, < and ==.

谢谢.

有一个古老的扩展名，允许以类似于python的方式执行此操作.您可以在此处找到它.

There is an ancient extension which allowed to do this in a manner similar to python. You can find it here.

话虽这么说，当今最好的选择是只使用常规方法进行比较.

That being said, your best bet nowadays is to just use regular methods for comparison.
