$array = array(
    array(
        'Id' => '1',
        'Description' => 'Get first Description',
        'Code' => 'GF',
        'Value' => 'Test 1'
    ),
    array(
        'Id' => '2',
        'Description' => 'Get second Description',
        'Code' => 'GF',
        'Value' => 'Test 2'
    ),
    array(
        'Id' => '3',
        'Description' => 'Get third  Description',
        'Code' => 'GF',
        'Value' => 'Test 3'
    )
);

function getArrayValue( $array , $id )
{
    foreach( $array as $a )
    {
        if( $a['Id'] == $id )
        {
            return $a;
        }
    }
    return 'U/N';
}

print_r( getArrayValue( $array , '2' ) );
