Extracting information from a static array Symfony 6

help me please!

I have a table in a database

Cars
====
1
2
3
4
4
2
3
1
4
2
===

I have a static array

cars = 
[
1 => 'BMW',
2 => 'Honda',
3 => 'Toyota',
4 => 'Mazda',
]

How can I change data from a table to data from a static array when displaying data?

I tried

private $car;
protected const cars = [
    1 => 'BMW',
    2 => 'Honda',
    3 => 'Toyota',
    4 => 'Mazda',
];

public static function getCars() {
    return self::cars;
}

public static function getCarCaption($car) {
    return self::cars[$car];
}
