spaces in array_keys($_GET)?

[yawnmoth]

Say I have the following script - test.php:

<?
if (count($_GET) != 0)
{
foreach(array_k eys($_GET) as $var)
{
echo "$var<br />";
}
}
?>

Is it possible for $var to contain a space? If I call "test.php?t his
is=a test" it gets turned into "test.php?this% 20is=a%20test" by the
browser and the output of the above is "this_is" - not "this is". If I
call "test.php?this+ is=a+test", the output is still "this_is".

I'm gonna guess it isn't possible - I just want to make sure.

It's mentioned in the php manual that: "A valid variable name starts with a
letter or underscore, followed by any number of letters, numbers, or
underscores." - so no, it's not possible, as space is not either number,
letter nor an underscroe. The reason for this is that a Php Fairy dies every
time someone uses a space in a variable name. So think about the faries,
don't use the spaces.

But the question is not about variable names, but about the content of
variables. And array keys can certainly contain spaces. It's the
automatic urlencoding by the browser that messes things up here. Try
playing around with urldecode(), for instance:

echo urldecode($var) . '<br />';

(untested).
