Question

I have a php file that needs to redirect to another, but I need to pass an array to the second file. How can I do this.

I know this is wrong, but I need something l

That's not how you do headers. it'd have to be

header("Location: someurl.php?vals=$arr");

however, this would just generat the URL

someurl.php?vals=Array

Note that a redirect by its nature cannot do a POST. it will result in a new GET request, meaning you have to pass data in the URL. If you have a very large url, you're almost guaranteed to lose most of it, as URLs have length limits.

However, if it's a short one, you can try something like:

$url = 'someurl.php?vals=' . url_encode(serialize($arr));
header("Location: $url");

and hope it works.
