PHP const数组 [英] php const arrays

问题描述

这是在php中将数组作为常量的唯一方法还是此错误代码:

Is this the only way to have arrays as constants in php or is this bad code:

class MyClass
{
    private static $myArray = array('test1','test2','test3');

    public static function getMyArray()
    {
       return self::$myArray;
    } 
}

推荐答案

您的代码很好-数组不能在5.6版之前的PHP中声明为常量，因此静态方法可能是最好的方法.您应该考虑通过注释将此变量标记为常量:

Your code is fine - arrays cannot be declared constant in PHP before version 5.6, so the static approach is probably the best way to go. You should consider marking this variable as constant via a comment:

/** @const */
private static $myArray = array(...);

在PHP 5.6.0或更高版本中，您可以声明数组常量:

With PHP 5.6.0 or newer, you can declare arrays constant:

const myArray = array(...);
