[Resolved] Checking all passed variable

[g7ibby]

How would I check any and all variables that are passed to a page via a form?

The number of variables, their names, and values will always be unknown.

The number of variables: count($GET)
How to get the names and values:

foreach ($_GET as $key=>$value) {
  echo($key." = ".$value."\n");
}

Or you can use print_r($_GET), but it's not separated into values there...

Change $GET[] to $POST[] depending on how the form is submitted.

You can also use:

extract($_GET);

or

extract($_POST);

Then you can just use the variables accordingly...

http://www.foo.com/foo.php?foo=1&fubar=Yes

would give you the following variables:
$foo = 1
$fubar = Yes

If you have more or less variables, then they would be defined the same way.

The only trick is that you should do error checking to see if there are any variables set in the URL to begin with...

list(arrayname)=each($HTTP_POST_VARS[])

that will store all passed variable to arrayname ,included variable name and its value

Thanks for all of the replies.

The foreach loop walks all of the variables with a action as needed.

Thanks Again
