否， 会话 是与全局可用变量不同.

No, session is different thing from a variable that is available globally.

$ GLOBALS

包含以下内容的关联数组 引用所有变量 当前在全球范围内定义 的脚本.变量名称是 数组的键.

An associative array containing references to all variables which are currently defined in the global scope of the script. The variable names are the keys of the array.

说明:

$GLOBALS是整个脚本中可用的关联数组，无需使用global $test

$GLOBALS is an associative array available throughout your script, there is no need to use global $test

注意:这是一个超级全局"，或 自动全局变量.这 只是意味着它在 脚本中的所有作用域.那里 不需要做全局变量到 在函数或方法中访问它.

Note: This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script. There is no need to do global $variable; to access it within functions or methods.
