$_REQUEST is not an indexed array, but associative. This means that values
can only be retrieved by keys.

Example:

The page is requested with a parameter foo with the value bar, as in:
page.php?foo=bar

If you want to print 'bar', you should do it like this:

print $_REQUEST['foo'];

But, you can get the values of the an associative array as an indexed array
through the array_values function:

$values = array_values($_REQUEST);

Afterwhich you can retrieve the values by their index:

print $value[1]; // 1 is the second index as 0 is always the first index

Please have a close look at the online manual starting at
http://www.php.net/manual/en/index.php to prevent asking basic questions
like this in the future.
