问题描述
在PHP中，我想知道GLOBAL和GLOBALS之间的区别.
In PHP I want to know the differences between the GLOBAL and GLOBALS.
一些例子:
print_r($GLOBALS);
推荐答案
与同一事物有两个不同的方面:全局变量.
That are two different things related to the same: global variables.
$GLOBALS -PHP superglobal 数组，表示可作为数组访问的全局变量表.因为它是超全局性的，所以随处可见.
$GLOBALS - PHP superglobal array representing the global variable table accessible as an array. Because it's a superglobal, it's available everywhere.
global -将特定的全局变量导入局部变量的关键字桌子.
global - Keyword to import a specific global variable into the local variable table.
然后您问:
错了，您可以使用$GLOBALS访问会话和cookie变量:
That's wrong, you can access session and cookie variables by using $GLOBALS:
$GLOBALS['_SESSION']['session_variable_name']
但是 $_SESSION 也是超全局变量，因此您无需使用任何$GLOBALS也不能global从任何地方访问会话变量:
However $_SESSION is a superglobal as well, so you don't need to use either $GLOBALS nor global to access session variables from everywhere:
$_SESSION['session_variable_name']
对 $_COOKIE 也是如此.
Same applies to $_COOKIE.
