How to find values in an array and update the array to keep only these values

Question

I have an array with values like these:

[oranges] => Array
    (
        [cost] => 0.56
        [quantity] => 6
    )

[pears] => Array
    (
        [cost] => 0.34
        [quantity] => 2
    )

I want to perform a search, get the search values using $_REQUEST (I've got to use $_REQUEST), then update the original array to display only the values the match the search. How can I do that?

PS: I need to be able to search the array based on item (oranges, pears, etc) and/or price and/or qty.

With my search form, the $_REQUEST is a variable with the in the following format:

Array
(
[item] => apple
[qty] => 2
[price] => 
)

Any suggestions?

hello you might want to handle this a bit better but something like this will do it:

$array[$_REQUEST['item']] = array(
                              "cost" => $_REQUEST['price'], 
                              "quantity" => $_REQUEST['qty']
                            );

Where $array equals the array you want to change.

Again I would lay this out a bit better and add some validation. (also avoid using request its a big security issue)

Hi Tom, thanks for the reply. I'm not sure I follow though: would this method update the array? Also, when I tested it, there was no output and it gave me an error if I didn't add "cost" and "quantity" in the search. Ideally I should be able to search by "item" and/or "cost" and/or "quantity" but if I use only one of those it should also work.

that's fine if you search by the key so "item", will be required. Then run different updates depending on what's set using "isset"
