phalcon framework -> edit model::find(); results in an foreach loop - object

Question

As http://docs.phalconphp.com/en/latest/reference/models.html#understanding-records-to-objects says, you can edit the objects once its loaded in the memory.
$settingCategories = SettingCategory::find();
foreach($settingCategories as $settingCategory){
if($settingCategory->type == "2"){
$settingCategory->type = "asd";
$settingCategory->intersection = "asd";
}else{
$settingCategory->type = "blaa";
$settingCategory->intersection = "blaa";
}
$settingCategory->type = "test";
}
$this->view->setVar("settingCategories",$settingCategories);
type is still its default value when I loop through it with volt:
{% for settingCategory in settingCategories %}
<div class="tab-content">
<h4>{{ settingCategory.name }}</h4>
<h4>{{ settingCategory.type }}</h4> --> still (int) integer!?
<h4>{{ settingCategory.intersection }}</h4> --> undefined!?
</div>
{% endfor %}

When you are modifying a variable inside a foreach, you are modifying a "temporary variable". What it means is that since it is only a copy of the real variable, when you change it, the real value inside the array isn't changed. Now, on to what you could do to solve this:
Setters/Getters
I personally prefer this one. If what you want to do is data transformation (I.E. you change the value of a field from one thing to another, and you want to use the new value in your code everywhere), I would use setters and getters. Here is an example:
// This is inside your model
protected $type;
public function getType()
{
if ($this->type === 2) {
return "asd";
} else {
return $this->type;
}
}
public function setType($type)
{
if ($type === 2) {
$this->type = "asd";
} else {
$this->type = 1; // or $type, or anything really :)
}
}
Of course, in your code, you'll have to change $category->type to $category->getType() and $category->setType($type), based on whether you are reading the value or assigning something to it.
The Quick and Dirty Way
Well, if your use case is different, you can use your current code block with a simple modification. Change your foreach to foreach($settingCategories as &$settingCategory). The ampersand makes the variable be passed into the block as a reference (I.E. it is not a copy like your current case). That means changing it will change the real value.
