How to format a json response in php - php

Question

I am new to php and am trying to return a json response in a particular structure. Here is what I have tried so far:
$response = array();
if ($con) {
$sql = "select * from admission_view";
$result = mysqli_query($con, $sql);
if ($result) {
$x = 0;
while ($row = mysqli_fetch_assoc($result)) {
$response[$x]['id'] = $row['id'];
$response[$x]['name'] = $row['name'];
$response[$x]['isActive'] = $row['isActive'];
$response[$x]['branchId'] = $row['branchId'];
$response[$x]['branch'] = $row['branch'];
$response[$x]['customerGroupId'] = $row['customerGroupId'];
$response[$x]['customerGroup'] = $row['customerGroup'];
$response[$x]['orderNo'] = $row['orderNo'];
$x++;
}
echo json_encode($response, JSON_PRETTY_PRINT);
}
} else {
echo "Connection error";
}
The code above returns this response:
However, instead of returning for example "branchId" and "branch" as individual properties, I want to pass their values inside a branchObject such that branch.id == "branchId" and branch.name == "branch".I mean, How may I return the response in the following structure:
And Here is how my database looks like:
How can I achieve this?

You ask for stuff that we are unsure if db result returns but as nice_dev pointed out, you need something like this:
$response = [];
if ($con) {
$sql = "select * from admission_view";
$result = mysqli_query($con, $sql);
if ($result) {
$x = 0;
while ($row = mysqli_fetch_assoc($result)) {
$response[$x]['id'] = $row['id'];
$response[$x]['name'] = $row['name'];
$response[$x]['isActive'] = $row['isActive'];
$response[$x]['branch']['id'] = $row['branchId'];
$response[$x]['branch']['name'] = $row['branch'];
$response[$x]['customerGroup']['id'] = $row['customerGroupId'];
$response[$x]['customerGroup']['name'] = $row['customerGroup'];
$response[$x]['customerGroup']['orderNo'] = $row['orderNo'];
$x++;
}
echo json_encode($response, JSON_PRETTY_PRINT);
}
} else {
echo "Connection error";
}
