Outputting an array element with a condition on another array element?

Question

PHP

There is this array $services:

Array
(
    [0] => Array
        (
            [id_room] => 1
            [id_service] => 1
            [service_name] => Обслуживание
        )

    [1] => Array
        (
            [id_room] => 2
            [id_service] => 1
            [service_name] => Обслуживание
        )

    [2] => Array
        (
            [id_room] => 1
            [id_service] => 2
            [service_name] => Развлечения
        )
)

You need to output service_nameif id_room, for example, is equal to 1.
I've tried outputting through a loop, checking like this:

for ($i = 0; $i < 3; $i++){
    if($services[$i]['id_room'] = 1){
        echo $services[$i]['service_name'];
    }
};

But it seems to me that this option will not work (it does not work), but I don’t really understand how to do it otherwise. At least tell me in which direction to google :)

Of course it won't work.

$services[$i]['id_room'] == 1
