Hi,
I need help determining if the list of parameters being passed in a url are valid

I have a list of valid parameters
define("validParms","item1,item2,item3");

I want a test to check the parameters being passed in a url
dosomething.php?item1=abc&item2=data
are legitimate.

ie
I want this to cause an error because it has an 'illegal' param
dosomething.php?item1=data&item2=data&noParam=data

So you want to throw an error if the query string (the $_GET array) contains a value that you are not expecting?

Try this:

<?php

$validParms = array("item1", "item2", "item3");
$invalidParms = array_diff(array_keys($_GET), $validParms);

if(count($invalidParms) > 0)
{
  echo "The following parameters are invalid:\n";
  print_r($invalidParms);
  die();
}


?>
