//我们应当使用require_once
//函数执行：php开辟新栈 各个栈间变量相互独立
//函数参数类型：array int float bool string object null 资源类型
//函数开头字母：_ a-z A-Z
//函数名不区分大小写 自定义函数中变量是局部的，函数外不生效

//global全局变量可以使用外部变量
//在函数中，我们不希望使用某个变量，或者是彻底的不在使用某个变量，可以使用unset($a);将该变量彻底删除
//函数默认值的问题：($a = 2){echo $a;}//2
//php默认值传递，需要地址传递可以使用&变量名
//常量：不需要$
//不能修改，需要赋初值，define or const ，全部大写用下划线间隔，不需要值变化，考虑使用常量
