Append new key to an existing array in an object - php

Question

I have an existing JSON array:
stdClass Object
(
[set] => Array
(
[0] => stdClass Object
(
[name] => agenda
)
[1] => stdClass Object
(
[name] => first aid
)
)
)
I need to add a new key to it, so the final JSON result is something like this:
set: [{
name: 'agenda',
value: 'Agenda'
}, {
code: 'first aid',
value: 'First Aid'
}],
This is what I've done so far:
$result = array();
foreach ($data->set as $k => $row) {
$result['name'][$k] = $row->name;
$result['value'][$k] = ucwords($row->name);
}
But I have ended up with:
Array
(
[name] => Array
(
[0] => agenda
[1] => aid kit
)
[value] => Array
(
[0] => Agenda
[0] => First Aid
)
)
How can I merge the above so the name and value keys are in pair rather then being separate?

Answer 1

Update $row directly to modify your existing $data:
foreach ($data->set as $row) {
$row->value = ucwords($row->name);
}
To do it the way you are attempting:
$result = $data;
foreach ($data->set as $k => $row) {
$result->set[$k]->value = ucwords($row->name);
}
Notice, $row is an object.

Your try this
$result = array();
$count = 0;
foreach ($data->set as $k => $row) {
$result[$count]['name'] = $row->name;
$result[$count]['value'] = ucwords($row->name);
$count++;
}
result this
Array
(
[0] => stdClass Object
(
[name] => agenda
[value] => Agenda
)
[1] => stdClass Object
(
[name] => first aid
[value] => First Aid
)
)

If you want to modify your existing object, you can just set the value property directly.
foreach ($data->set as $row) {
$row->value = ucwords($row->name);
}
If you want to create a result without modifying your original object or leaving references to its internal objects, you can clone each of the internal objects and add the new properties to the cloned objects.
$result = array();
foreach ($data->set as $k => $row) {
$obj = clone $row;
$obj->value = ucwords($row->name);
$result[$k] = $obj;
}
