php中的$_ENV存储了一些系统的环境变量,因环境不同而值不同.
但有时候$_ENV是空的,可能有以下原因:
在php.ini中的variables_order值为“GPCS”,也就是说系统在定义PHP预定义变量时的顺序是GET,POST,COOKIES,SERVER,没有定义Environment(E),你可以修改php.ini文件的variables_order值为你想要的顺序,如:“EGPCS”.这时,$_ENV的值就可以取得了
EGPCS值(EGPCS是Environment、Get、Post、Cookies、Server的缩写 -- 这是PHP中外部变量来源的全部范围).

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
