Session variable $_Session[] - How global?

Sorry if this is a dumb question but here goes:

When reading about programming dynamic web pages the author often refers to a PHP session variable $_SESSION[ArrayKey]. The livecode dictionary refers to a global variable with the same name i.e $_SESSION[ArrayKey]. Are these the same global variable or do they just exist within their respective environments?
