|
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 POST uploaded file information. Note that the
|
|
order of the letters matters, as when using "gp", the POST
|
|
variables will overwrite GET variables with the same
|
|
name. Any other letters than GPC are discarded.
|
|
</simpara>
|
|
<simpara>
|
|
The <parameter>prefix</parameter> parameter is used as a variable
|
|
name prefix, prepended before all variable's name imported into the
|
|
global scope. So if you have a GET value named "userid", and provide
|
|
a prefix "pref_", then you'll get a global variable named
|
|
$pref_userid.
|
|
</simpara>
|
|
<simpara>
|
|
If you're interested in importing other variables
|
|
into the global scope, such as SERVER, consider using
|
|
<function>extract</function>.
|
|
</simpara>
|
|
<note>
|
|
<para>
|
|
Although the <parameter>prefix</parameter> parameter is
|
|
optional, you will get an
|
|
<link linkend="internal.e-notice">E_NOTICE</link> 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
|
|
<link linkend="ini.error-reporting">error reporting</link>
|
|
level.
|
|
</para>
