Hi Larry, Tuesday, June 19, 2007, 2:55:07 AM, you wrote: > Perhaps you're looking for in_array()? If only it was that simple! But pray tell how an in_array search is going to find: $userparam = "test['bob'][]"; within: Array ( [test] => Array ( ['bob'] => Array ( [0] => red [1] => green [2] => blue ) ) ) ? The problem is that $userparam in the example above needs to be expanded out into a form that $_POST can be searched for it. Or vica versa.
