Question

I have an array in PHP, here is a snippet:

$locations = array(
    array(
        "id" => 202,
        "name" => "GXP Club - Fable"
    ),

    array (
        "id" => 204,
        "name" => "GXP Club - Gray"
    )
);

What I know (from a GET) is the ID (202). What I would like to display is
“Showing results for ”
( where $locations[?][id] = $_GET['id'] { echo $locations[?][name] } )
– if you will pardon my use of pseudo code.

Not sure what function is best or if I need to loop over the whole array to find that. Thanks.

Edit: for further clarification. I need to learn the [name] given the [id]

Answer 1

foreach( $locations as $arr ) {
    if($arr['id'] == $_GET['id']) {
        echo $arr['name'];
        break;
    }
}

That should do the trick.
