  1. Hello, I'm very happy to know about the urlencode and urldecode functions on p.105, but I got a little bit confused regarding the tip there. It says: "Values sent directly from a form are automatically URL-encoded prior to being sent and decoded upon arrival at the receiving script. Y ou only need the urlencode() function to manually encode data (as in the example)." So, why do I need to manually encode the data while values sent from a form are actually URLencoded automatically? Sorry for this dumb question but I have been thinking about this for half an hour, sorry... Though
