PHP If else and some logics - php

Question

I just having some problem of if/else or somewhat logical things in here, I have a fullcalendar that shows all the date that being reserve, I limit the reserve by 5 per date, but when I having a 2 or more reserved on the date and having reserve by other date, It gives me the same result as 4.
global $db;
$data = array();
$query = "SELECT * FROM reserve_master
INNER JOIN reserve_details
on reserve_master.reserve_id = reserve_details.reserve_id
INNER JOIN reserve_indicator
on reserve_master.reserve_id = reserve_indicator.reserve_id
WHERE reserve_indicator.touserid = '$id'
AND reserve_master.type = 'Repair' ";
$res = mysqli_query($db,$query);
$count = mysqli_num_rows($res);
$count = 5 - $count;//count the available slot
$date_changed = "";
$reserve_id = 0;
foreach ($res as $row)
{
date_default_timezone_set('Asia/Manila');
$current_timestamp = strtotime($row["dateend"] . '+1 day');
$time = date("Y/m/d",$current_timestamp);
if($row["datestart"] == $date_changed)
{
//This is for avoiding repeating graph on fullcalendar
}
else
{
if(empty($count))
{
$count = '0';
}
else
{
$count;
}
$data[] = array(
'id' => $row["reserve_id"],
'title' => $count,
'start' => $row["datestart"],
'end' => $time,
'color' =>getColor($row["status"])
);
$date_changed = $row["datestart"];
$reserve_id = $row["reserve_id"];
}
}
echo json_encode($data);

All i had tried is to get the right available on the 2nd of febuary 2018 and not the others.

Answer 1

The code is mess, I'm very sorry;
Problem is solved already;
I use eventLimit on fullcalendar and set it to 1
Count = 5 not subtracted by the num_rows
and few set on if-statement
Few answer I used rows and res as it is easy to indicate for results and rows, and i used it same as other queries.
Thank you.
