PHP常量包含有数组？ [英] PHP Constants Containing Arrays?

问题描述

这失败：

 define('DEFAULT_ROLES', array('guy', 'development team'));

显然，常量不能抱阵列。什么是解决这个问题的最好方法？

Apparently, constants can't hold arrays. What is the best way to get around this?

define('DEFAULT_ROLES', 'guy|development team');

//...

$default = explode('|', DEFAULT_ROLES);

这似乎是不必要的努力。

This seems like unnecessary effort.

推荐答案

注意：虽然这是顶级投回答，这是值得注意的是，在PHP 5.6+，你可以有常量数组 - 的见下文安德烈·福尔兹的回答

NOTE: while this is the top voted answer, it's worth noting that in PHP 5.6+ you can have const arrays - see Andrea Faulds' answer below.

您也可以序列化数组，然后把它放到常数：

You can also serialize your array and then put it into the constant:

# define constant, serialize array
define ("FRUITS", serialize (array ("apple", "cherry", "banana")));

# use it
$my_fruits = unserialize (FRUITS);
