Special character (+) gets lost when transmitted as GET parameter


I have to process URLs having + characters and blanks in their GET parameter. Unfortunately, PHP is replacing the + characters by blanks. By the way, I access the GET parameters using $_GET[parameter].

Is there a way to prevent PHP from converting + characters in a URL to blanks?

Thanks a lot.

Does it mean that there is only the way to use urlencode() and urldecode() for every sent or received GET-Parameter?
At least for preperation of references, like:

echo "<a href=\"test.php?id=" . urlencode($id) . "\">";

or when using JavaScript:

location.href="test.php?id=" + encodeURIComponent(id);

urencode as u've seen in php manual, converts special characters by % and two hex digits. If it is vital for you to get all the special characters in your GET, then u got to use URL encode. but if u r planning to use GET with "id" or "pageNum" or numrical stuff like that, your don't have to use it !!!

Since I have + characters in my GET parameters I need to use urlencode(). Otherwise they are lost.
