Group variables and loop through them - php

Question

When I just had single variables I used the compact array function to create an array containing variables and their values and looped through them, but now I have multiple variables in a 'group' to loop through:
$details_room_name_1
$details_room_photo_1
$details_room_capacity_seated_1
$details_room_name_2
$details_room_photo_2
$details_room_capacity_seated_2
$details_room_name_2
$details_room_photo_2
$details_room_capacity_seated_2
I want to loop through each 'GROUP' (room) of variables at a time
loop
echo room name
print_r room photo array
echo capacity

Using array is better (the best) solution for this task, but if the data structure has to be as you wrote (I don´t know Wordpress), you can use st. like this ugly code.
<?php
$details_room_name_1 = 'room 1';
$details_room_photo_1 = 'photo 1';
$details_room_capacity_seated_1 = 1;
$details_room_name_2 = 'room 2';
$details_room_photo_2 = 'photo 2';
$details_room_capacity_seated_2 = 5;
$details_room_name_3 = 'room 3';
$details_room_photo_3 = 'photo 3';
$details_room_capacity_seated_3 = 8;
for ($i = 1; $i <= 10; $i++) {
if (!isset(${'details_room_name_' . $i})) continue;
echo 'room name: ' . ${'details_room_name_' . $i} . '<br>';
echo 'room photo: ' . ${'details_room_photo_' . $i} . '<br>';
echo 'room capacity: ' . ${'details_room_capacity_seated_' . $i} . '<br><br>';
}
/*
returns
room name: room 1
room photo: photo 1
room capacity: 1
room name: room 2
room photo: photo 2
room capacity: 5
room name: room 3
room photo: photo 3
room capacity: 8
