any idea?

To replace %20 with +

$url = str_replace("%20", "+", $url);

To change the plus into a space for your queries:

$url = urldecode($url);

Use urlencode to encode. The decoding will happen automatically, you just need to read the value from $_GET.

encode your "+" using "%2B". or use rawurldecode instead of urldecode. If that's not what you need than please supply some code so I can be more specific.

You don't need to decode it if you just use the $_GET array: http://ca.php.net/manual/en/reserved.variables.get.php

If you use the link you mentioned, you can access the query using echo $_GET['q'] will result in iphone 4, then you can use explode(' ', $_GET['q']) which will result in array('iphone', '4').
