Problem with 302 redirect

I am using a 302 redirect to one of my page as I don't want the page to be indexed by google. I am using the following code to redirect :

 
$url = "http://www.mysite.com/test_page.php" ;
header('location:' . $url .''); 

PHP:

Is the code above considered to be a 302 redirect as I just came to know that the page I am redirecting to i.e test_page.php is indexed by google. If it is not, can anyone give me an example of a 302 redirect ?

Thanks

 

Is there anyway I can prevent this from spidering? and If I do so; will there be any penalty by google or something similar?

Thanks,

 

you could disallow * in your robots.txt

 

My case is a little different. The variable $url actually gets value from the database and lets say there are 100 urls or 1000, its hard to disallow all of them in robots.txt
