Redirect to variable
how do you redirect stdout into a variable. whenever I try I get an ambiguous redirect error
I am trying to validate some user input and failing miserably.
cal $MONTH $YEAR | grep -c "$DAY"
if the above is 1 then it is valid if 0 then not valid. I have been trying to redirect the output into a variable but get the error. Any ideas?
Many Thanks.

http_redirect
HTTP_REDIRECT(3) 1 HTTP_REDIRECT(3)
http_redirect - Issue HTTP redirect
SYNOPSIS
bool http_redirect ([string $url], [array $params], [bool $session = false], [int $status])
DESCRIPTION
Redirect to the given url.
The supplied $url will be expanded with http_build_url(3), the $params array will be treated with http_build_str(3) and the session iden-
tification will be appended if $session is true. The HTTP response code will be set according to $status. You can use one of the redirect
constants for convenience. Please see RFC 2616 for which redirect response code to use in which situation. By default PHP will decide which
response status fits best.
To be RFC compliant, "Redirecting to <a>URL</a>." will be displayed, if the client doesn't redirect immediately, and the request method
was another one than HEAD.
A log entry will be written to the redirect log, if the INI settinghttp.log.redirect is set and the redirect attempt was successful.
PARAMETERS
o $url
- the URL to redirect to
o $params
- associative array of query parameters
o $session
- whether to append session information
o $status
- custom response status code
RETURN VALUES
Returns FALSE or exits on success with the specified redirection status code. See the INI settinghttp.force_exit for what "exits" means.
EXAMPLES
Example #1
A http_redirect(3) example
<?php
http_redirect("relpath", array("name" => "value"), true, HTTP_REDIRECT_PERM);
?>
The above example will output:
HTTP/1.1 301 Moved Permanently
X-Powered-By: PHP/5.2.2
Content-Type: text/html
Location: http://www.example.com/curdir/relpath?name=value&PHPSESSID=abc
Redirecting to <a href="http://www.example.com/curdir/relpath?name=value&PHPSESSID=abc">http://www.example.com/curdir/relpath?name=value&PHPSESSID=abc</a>.
