Appending SQL to existing associative array - php

Question

Learning PHP and creating associative arrays.
Trying to create associative array that describes an activity. An activity for this example is 354 and 355.
This is my current code:
$query = $db->prepare('SELECT item_id FROM kh_program_item_info WHERE '. $where);
$query->execute();
if($query->rowCount() > 0){
while($john = $query->fetch(PDO::FETCH_OBJ)){
$key1 = $john->item_id;
$report-> $key1= array();
}
foreach ($report as $key=>$johnval) {
$where = 'item_id = ' . $key;
$query = $db->prepare('SELECT activity_desc, DATE_FORMAT(activity_date,"%d/%m/%Y") AS activityDate FROM kh_program_items WHERE '. $where);
$query->execute();
$results = $query->fetch(PDO::FETCH_OBJ);
$report->$key = $results;
echo '<pre>';
echo print_r($report);
echo '</pre>';
}
} else {
echo '<p>there are no activities</p>';
}
this will yield results.
stdClass Object
(
[354] => stdClass Object
(
[activity_desc] => <p>Send Activity</p>
[activityDate] => 08/11/2016
)
[355] => stdClass Object
(
[activity_desc] => <p>Send Activity 2</p>
[activityDate] => 11/11/2016
)
)
I am now trying to add more information for 354 and 355.
I have revisited the code and here is new code:
$query = $db->prepare('SELECT item_id FROM kh_program_item_info WHERE '. $where);
$query->execute();
if($query->rowCount() > 0){
while($john = $query->fetch(PDO::FETCH_OBJ)){
$key1 = $john->item_id;
$report-> $key1= array();
}
foreach ($report as $key=>$johnval) {
$where = 'item_id = ' . $key;
$query = $db->prepare('SELECT activity_desc, DATE_FORMAT(activity_date,"%d/%m/%Y") AS activityDate FROM kh_program_items WHERE '. $where);
$query->execute();
$results = $query->fetch(PDO::FETCH_OBJ);
$report->$key = $results;
$query = $db->prepare('SELECT info_value FROM kh_program_item_info WHERE '. $where .' AND info_type="program_category"');
$query->execute();
$info_value = $query->fetch(PDO::FETCH_OBJ);
$where = 'category_id = ' . $info_value->info_value;
$query = $db->prepare('SELECT category_name FROM kh_program_categories WHERE '. $where);
$query->execute();
$actcategories = $query->fetch(PDO::FETCH_OBJ);
$report->$key = $actcategories;
echo '<pre>';
echo print_r($report);
echo '</pre>';
}
} else {
echo '<p>there are no activities</p>';
}
this will obviously overwrite what I have created and yield the following results:
stdClass Object
(
[354] => stdClass Object
(
[category_name] => Parent Input
)
[355] => stdClass Object
(
[category_name] => Children's Menu
)
)
The problem is $myactivity->$key = $actcategories;.
How do I append to the end without overwriting information?
I need to yield this result
stdClass Object
(
[354] => stdClass Object
(
[activity_desc] => <p>Send Activity</p>
[activityDate] => 08/11/2016
[category_name] => Parent Input
)
[355] => stdClass Object
(
[activity_desc] => <p>Send Activity 2</p>
[activityDate] => 11/11/2016
[category_name] => Children's Menu
)
)
Thanks in advance.

You'll need to build your array first and then, send it to the object.
i.e. :
foreach ($report as $key=>$johnval) {
$where = 'item_id = ' . $key;
$query = $db->prepare('SELECT activity_desc, DATE_FORMAT(activity_date,"%d/%m/%Y") AS activityDate FROM kh_program_items WHERE '. $where);
$query->execute();
// build first array
$result_first_query = $query->fetch(PDO::FETCH_OBJ);
$query = $db->prepare('SELECT info_value FROM kh_program_item_info WHERE '. $where .' AND info_type="program_category"');
$query->execute();
$info_value = $query->fetch(PDO::FETCH_OBJ);
$where = 'category_id = ' . $info_value->info_value;
$query = $db->prepare('SELECT category_name FROM kh_program_categories WHERE '. $where);
$query->execute();
// build second array
$result_second_query = $query->fetch(PDO::FETCH_OBJ);
// put them together in $report->$key
$report->$key = $result_first_query + $result_second_query;
echo '<pre>';
print_r($report);
echo '</pre>';
}
Hope it helps.
