Finally I was able to solve the problem and I'm posting the solution here just in case someone else finds the same problem when passing arrays in URL. The trick is to use serialize/unserialize.

So in the passing to the URL you use:

PHP Code:

$url = urlencode(serialize($array)) 


and to restore the variable you use

PHP Code:

$var = unserialize(urldecode($_GET['array'])) 


Thank you very much Lynne.
