$_REQUEST is a PHP superglobal; you always have access to it.

<soapbox>
TLDR: You can do what you need to with $_REQUEST, but may incur technical debt.

That said, one problem I periodically run into is that encapsulation
is repeatedly broken whenever you are forced to look at globals
instead of function arguments.  I have at least one place in my code
where I hack the $_REQUEST variable to get the desired behavior.

$reqfoo = $_REQUEST['foo']
$_REQUEST['foo'] = 'bar';
do_something();
$_REQUEST['foo'] = $reqfoo;
do_something_else();
