Return Values from ID in PHP Array

I have an array in PHP structured like below. If I return the 'StateID' from a REST call, how can I use the ID to get the abbreviation and state name for that ID? For example an ID of '1' would return an abbreviation of Name = Alabama and Abbreviation = AL..

Array:

array(1) { ["StateList"]=> array(50) 
    { [0]=> array(3)
        { ["StateID"]=> int(1) ["Name"]=> string(7) "Alabama" ["Abbreviation"]=> string(2) "AL" } 
      [1]=> array(3) 
        { ["StateID"]=> int(2) ["Name"]=> string(6) "Alaska" ["Abbreviation"]=> string(2) "AK" }....

$id = 1; // Searched ID
foreach ($array['StateList'] as $key => $value) {
    if ($value['StateID'] == $id) {
        echo $value['Name'];
        echo $value['Abbreviation'];
        break;
    }
}

Hope it helps, just a matter of one simple loop.

PS. This is a linear solution. Of course You can make a function out of it:

function FindId($array, $id) {
    foreach ($array as $key => $value) {
        if ($value['StateID'] == $id) {
            return $value;
            break;
        }
    }
    return false;
}
$result = FindId($array['StateList'], 1);
print_r($result);
