php – 是否可以将数组声明为常量

参见英文答案 > PHP Constants Containing Arrays?                                    20个
我们可以定义一个常量

define("aconstant','avalue');

我们不能像下面这样定义数组吗？

define("months",array("January", "February", ---); 

解决方法:

更新：在PHP 7(reference)中可以实现

// Works as of PHP 7
define('ANIMALS', array(
    'dog',
    'cat',
    'bird'
));
echo ANIMALS[1]; // outputs "cat"

原始答案

来自PHP.net …

The value of the constant; only scalar and null values are
allowed. Scalar values are integer, float, string or boolean values.
It is possible to define resource constants, however it is not
recommended and may cause unpredictable behavior.

$months = array(“January,”February“,…)将会很好.
