I need to know wich is the best way to send variables through an URL,that if
the variables are of the string type, and what if the variable has spaces
like $string='this is a test'.
I have read about the use of urlencode(), but I have a strange behaviour
using this function, sometimes it work and sometimes not.
for an example I send the variable $user='user 1', and in the url there
appears user=user+1 (which I think is correct) but when I read the variable
in the php page it displays user+1 (doesn´t it has to return to user '1'?).
