- <link linkend="language.variables.superglobals">Superglobal arrays</link>.
- This means you cannot do things like <varname>${$_GET}</varname>. If you are
- looking for a way to handle availability of superglobals and the old
- <varname>HTTP_*_VARS</varname>, you might want to try
- <link linkend="language.references">referencing</link> them.

+ within functions or class methods.
