Named Arguments Named arguments allow passing arguments to a function based on the parameter name rather than position. This way, function calls become self-documenting and arguments order becomes arbitrary.
named arguments 命名属性 推荐 好处不用多说了,语法能力提升,自然编程的自由度,便捷度也更好 这一项在面向对象语言中比较常见,类似于C++中的重载就允许实现类似的作用,但是C++的重载实现的能力更强一些,在swift中也是有类似的语法实现。 这个更新总体来说是预言特性上的补足,在7X版本中虽然IDE可以补充参数名显示,...
通过指定参数的名称,我们可以在调用函数时不必考虑参数的顺序,这在处理具有大量可选参数的函数时尤为方便。Named Arguments的引入不仅简化了函数调用的语法,还提高了代码的可读性。 除了上述特性之外,PHP 8还带来了一系列其他改进,包括Match表达式、Constructor Property Promotion、Attributes等。这些新特性都为开发者提供了...
