PHP7之常量数组

php7之前define只能是键值对，而php7里可以把数组加进define

<?php
/**
 * Created by PhpStorm.
 * User: bee
 * Date: 2016/4/23
 * Time: 1:27
 */
define('NAME',[
    'lig','bee','arr'=>array('ligbee'),array('lig','bee'),'w'
]);
echo NAME[0];
echo '<br>';
echo NAME['arr'][0];
echo '<br>';
print_r(NAME[2]) ;
//array定义的会被直接忽略
//若'arr'后没有值，NAME[2]也会报错
print_r(NAME[3]) ;
define('DIR','every');
echo '<br>'.DIR;
