Get variable in sql statment and use in php - php

Question

The function below generates a table like the image below.
The location_id is being accessed but I would like to use this ID again at the bottom of the table in a link. See the LOCATION_ID at the bottom of the function.
Im not sure how to do this.
function countAppointment2() {
require 'config.php';
$data = array();
$date_list= array();
$sql_date_list ="SELECT start_date from appointment GROUP BY start_date";
$result_date_list = mysqli_query($conn, $sql_date_list);
$sql_loc_list = "SELECT `name` FROM `location` GROUP BY `name`";
$result_loc_list = mysqli_query($conn, $sql_loc_list);
$k=0;
while ($row =mysqli_fetch_assoc($result_loc_list)){
$data +=[$row['name']=>array()];
if($k==0){
while($row2 =mysqli_fetch_assoc($result_date_list)){
array_push($date_list,$row2['start_date']);
$data[$row['name']]+=[$row2['start_date']=>0];
}
$k++;
}else{
foreach($date_list as $date){
$data[$row['name']]+=[$date=>0];
}
}
}
$sql_getdata = "SELECT t2.name as loc_name, t1.start_date,t1.location_id, COUNT(t1.location_id) AS count FROM appointment t1 JOIN location t2 ON t1.location_id = t2.id GROUP BY t1.location_id,t1.start_date";
$result = mysqli_query($conn, $sql_getdata);
while($row =mysqli_fetch_assoc($result)){
$data[$row['loc_name']][$row['start_date']]=$row['count'];
}
$table="<table class='table table-bordered'>";
$table.="<thead><tr>";
$table.="<th>Dealership Location</th>";
foreach ($date_list as $date) {
$edate = date("d/m/Y", strtotime($date));
$table.="<th>".$edate."</th>";
}
$table.="</tr></thead>";
foreach ($data as $key=>$date) {
$table.="<tbody><tr>";
$table.="<td>".$key."</td>";
foreach($date as $key2=>$count){
$table.="<td>".$count."</td>";
}
$table.="</tr>";
}
$table.="</tbody></table>";
echo $table;
}

Change
$data[$row['loc_name']][$row['start_date']]=$row['count'];
to
$data[$row['loc_name']][$row['start_date']] = [
'count' => $row['count'],
'location_id' => $row['location_id']
];
Then replace the code in the loop to:
$table.="<td>".$count['count']."</td>";
Essentially changing it from a single value to an array.
