<simpara>
Imports GET/POST/Cookie variables into the global scope. It is
useful if you disabled
<link linkend="ini.register-globals">register_globals</link>,
but would like to see some variables in the global scope.
</simpara>
<simpara>
Using the <parameter>types</parameter> parameter, you can
specify, which request variables to import. You can use
'G', 'P' and 'C' characters respectively for GET, POST and
Cookie. These characters are not case sensitive, so you
can also use any combination of 'g', 'p' and 'c'. POST
includes the uploaded file informations. Note, that the
order of the letters matters, as using "gp", the POST
variables will overwrite GET variables with the same
name. Any other other letters then GPC are discarded.
</simpara>
<note>
<para>
Although the <parameter>prefix</parameter> argument is
optional, you will get a notice level error, if you
specify no prefix, or specify an empty string as a
prefix. This is a possible security hazard. Notice
level errors are not displayed using the default
error reporting level.
</para>
</note>
<informalexample>
<programlisting role="php">
// This will import GET and POST vars
// with an "rvar_" prefix
import_request_variables("gP", "rvar_");
</programlisting>
