Assigning to $_POST?

[sit]

Hello,
It's my first week with PHP.
Can I assign to $_POST? Is this considered good practice?

I want to do some pre-processing on a couple of the parameters then pass $_POST on to another script.

Yes you can. It is quite simply an array and can be acted upon like any other array. It shouldn't be necessarry to do so as you can quite easily do
$post_copy=$POST;
and then work with $post_copy
This way you always have the original values that were sent to the script held in $POST;

You can also change the value in $_POST itself. Example if you have a user enter a date such as "25th July 2003" in your "birthday" form field and your code must work with valid timestamps you can do the following:

$_POST["birthday"] = strtotime($_POST["birthday"]);

This would be discouraged - The best way is still like what OhLordy mentioned - to preload the $_POST variables into a local scope variable and work on those as it will not confuse you when your code logic grows.

Thank you. I will copy the variables as per both of your replies.
