$HTTP_SERVER_VARS['SCRIPT_FILENAME'] - getting all GET vars too?

[mr_burns]

Hi,

I am using $HTTP_SERVER_VARS['SCRIPT_FILENAME'] to get the name of the
current web page. How do I also get the GET variables using PHP as a
complete string. For example:

'?first=12&second=value&third=2.99'

As I dont know what the variables may I cant simply use $_GET. Ideally
something like FOR EACH $_GET to generate the GET part of the url. Any
ideas? Cheers

Burnsy

$_SERVER would be preferred, but it's the same info.

Look at $_SERVER['QUERY_STRING']

phpinfo() is useful for dumping out all the superglobals, or you could just
var_dump($_SERVER) etc.; you can then see which ones may have the information
you need.

Well, yes exactly that.

foreach ($_GET as $key => $val)

... same as any associative array. There could be arrays in there though which
are treated a bit differently. It's all available in $_SERVER['QUERY_STRING'],
but looping through $_GET may be useful if:

(a) you want to modify/add/remove some of the values, but keep the rest
(b) you want to change the separator, e.g. from & to ;

Same info, but not the same scope. $_SERVER is superglobal, the old
$HTTP_* arrays are not.

This can also be done with modifying 'arg_separator.input' if possible.

True.

Well, having that set might be _why_ you'd want to rewrite URLs to use ';'
instead of '&' (which browsers tend to send), rather than _how_. I tend to have
arg_separator.input set to '&;', and write out URLs separated with ';' mostly
because it's easier than escaping & into &amp; all over the place.
arg_separator.output handles anything where PHP constructs URLs, but I think
that's mostly just the form rewriting it does for cookie-less sessions.
