Since PHP 4.1.0, the preferred method for retrieving
|

<link linkend="language.variables.external">external variables</link> is

with the superglobals mentioned below. Before this time, people relied

<link linkend="language.variables.predefined">predefined

If you're not using them, it's recommended to turn them off,

for performance reasons. Instead, use the superglobal arrays,
