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;
