不,这是不可能的.从手册：
Constants Syntax
原文链接：https://www.f2er.com/php/134919.htmlOnly scalar data (boolean,integer,float and string) can be contained in constants. It is possible to define constants as a resource,but it should be avoided,as it can cause unexpected results.
如果需要设置一组已定义的常量,请考虑创建一个类并使用class constants填充它.手册中略有修改的示例：
class MyClass
{
const constant1 = 'constant value';
const constant2 = 'constant value';
const constant3 = 'constant value';
function showConstant1() {
echo self::constant1 . "\n";
}
}
echo MyClass::constant3;
