Const数组在php 5.6中运行？

Question

In the php manual, it is stated in user contributed notes that const array is now allowed. I even checked other posts here in stackoverflow and they said the same. I tested the following code:

<?php

class Constants{
      const test = array("a"=>"apple","b"=>"ball","c"=>"car");
}
echo Constants::test["b"];
echo Constants::test["c"];
echo Constants::test["a"];
?>

Output:

ball
car
apple

The above code works. However This doesn't work if I use define('test',array("a"=>"apple","b"=>"ball","c"=>"car") outside of the class. Is this a new undocumented change or happening only in my setup?

My setup is php 5.6.1(32-bit thread safe) and apache 2.4.10 (32-bit) on windows 7 x64. I downloaded them from the their respective sites directly. I didn't use any WAMP stacks.

Also note that I am using netbeans 8.0.1 IDE for hints and it shows this error. Anyone know how to remove it?

Syntax error

Answer 1

Apparently if I use const outside of a class, the error in netbeans IDE won't show up.

const test = array("a"=>"apple","b"=>"ball","c"=>"car");
echo test["b"];
echo test["c"];
echo test["a"];

This should work!
