The context of a variable depends on whether it's defined in the base of the document, inside a function, or inside a class. There are three types of scopes: local, global and superglobal. Superglobals exist at the server level. Globals exist at the document base level. Locals exist at the function or class level for each instance of that function or class. Scope can be set to global by using the 'global' keyword or using the $GLOBALS array when defining the variable, and superglobals can be set using the reserved variable name ($GLOBALS is itself a superglobal). Then of course there's passing by reference...
