Adding array elements with a for(reach) loop - php

Question

(First a bit/lot of context at the bottom is the question)
I am writing an API that returns a planning amongst other things. The response is in JSON and should be as followed:
"Planning":
[
{
"Name": "Overview",
"Dates":
[
{
"Date": "yyyy-mm-dd",
"Division1": "type",
"Division2": "type"
},
{
"Date": "yyyy-mm-dd",
"Division1": "type",
"Division2": "type"
},
...
]
},
{
"Name": "Division1",
"Dates":
[
{
"Date": "yyyy-mm-dd",
"Type": "type",
"Description": "type"
},
...
]
},
...
There is the standard blok "Name": "Overview" this is always returned, and for each division the requester is a part of, a block with "Name":"Divisionname" is added to the response.
The issue I have is that the amount or names of the divisions aren't set in stone. There can be more or less depending on the deployment.
To cover for this I wrote the following code:
<?php
...
$stmt = $conn->prepare("SELECT `idDivision` FROM Division;");
$stmt->execute();
$stmt->bind_result($idDivision);
while($stmt->fetch()){
$Divisions[] = $idDivision;
$$idDivision = array();
}
...
?>
This should create an array for each division with the array name being the id of that division (correct?).
Then I get the planning data from the DB which i store in the multiple arrays that I will later use for the response building:
<?php
$stmt->bind_result($type, $date, $idDivision, $day, $description, $note);
while($stmt->fetch()){
if(checkarray($date, $arr_date) != true){
array_push($arr_date, $date);
array_push($arr_day, $day);
}
array_push($$idDivision, $type); //This should push it into the correct array.
}
?>
At the end I want to combine all this into the respons ofcourse (This is where I am lost):
<?php
for($i = 0; $i <= count($arr_date); $i++){
$planning[0]['Dates'][] = array(
"Date" => $arr_date[$i],
// How to add every division with "arrayname" => "$type" here?
);
}
?>
As in the comment above, i don't know how to add a key:value for each division that i found dynamically so that it becomes:
<?php
for($i = 0; $i <= count($arr_date); $i++){
$planning[0]['Dates'][] = array(
"Date" => $arr_date[$i],
"Division1" => $value,
"Division2" => $value,
"Division3" => $value,
// and so on for every division
);
}
?>
Is there a way to do this or should I even go about doing this a different way? I feel like I should/could use the $Divisions array.

Try out this.
for($i = 0; $i <= count($arr_date); $i++){
$planning[0]['Dates'][$i]["Date"] = $arr_date[$i];
for($j=0;$j<count($division);$j++){
$planning[0]['Dates'][$i]["division$j"] = $division[$j];
}
}
?>
