PDO retrieve all fields with value 1 and echo with alternate name - pdo

Question

i have a table (facility) in which field names are swimming_pool, restaurant, WiFi, library etc.
if a particular house having only two of those facilities available, i give those available field names value 1 and if not 0.
I want to retrieve all the field names with value 1 and echo each field with value 1 with an alternate name.
here is what i want to achieve
$st = $db->prepare(select * from facility where house_id = ?);
$st->execute(array($_GET['house_id']));
$row = $st->fetch();
from above i have to select all fields with value 1. And for all those fields with value one i have to echo name (for example: if swimming_pool value is 1 i have to echo Swimming Pool, if it is 0 then check for the next column)
i hope you understood my goal.

I hope I solved your question? I didn't test it yet, so if there might be a problem, do a comment.
<?php
/*
* Sample Link: web.com/index.php?house_id=1&search=1,0,0,1

/*

//Explode the $_GET['search'] to create an array
$fields_to_search = explode(",",$_GET['search']);
//Manually set the fields
$db_fields = [

//Create a counter as basis to store if the Link is 1 or 0, then pass it to $db_fields[]
$counter = 0;
foreach($fields_to_search as $field) {
//Check if $field is 1
if($field == 1) {
//Then pass it to $table_to_be_selected and add a COMMA
$fields_to_be_selected .= $db_fields[$counter].",";
}
$counter++;
}
//Remove the last COMMA
$fields_to_be_selected = substr($fields_to_be_selected,0,-1);

$query = sprintf("SELECT %s FROM `facility` WHERE `house_id` = ?",$fields_to_be_selected);
$stmt = $db->prepare($query);
$stmt->execute(array($_GET['house_id']));
$rows = $stmt->fetchAll();
//It will only print the selected fields
print_r($rows);
