QuestionPHP7, uasort method, return new instance Pin
jkirkerx23-Apr-21 9:12
professionaljkirkerx23-Apr-21 9:12 
I wrote this PHP 7.14.4 class to represent an object of Keys and Values, made up of Key Value. It uses IteratorIterator, which I have found to contains about 15 useful methods to do things like count(), append(), move() and uasort(). I wrote this sort of piecing together some concepts, and thought it would be a nice method to have in my swiss army knife.

I get this error message, and I understand what it says, and I have 1/2 a clue on how to fix it, but I can't visualize how to return a new instance of KeyValue.

Fatal error: Uncaught TypeError: Return value of KeyValues::uaSort() must be an instance of KeyValues, none returned in C:\App\Dev\PCAD\models\keyValue.model.php:52 Stack trace: #0 C:\App\Dev\PCAD\api\prices\priceSetUpdate.api.php(61): KeyValues->uaSort() #1 {main} thrown in C:\App\Dev\PCAD\models\keyValue.model.php on line 52

I called the method like this below ....
I'm surprised PHP didn't complain about my merge method concept that I wrote. I included the extra code so you can get an idea of what I'm doing and how I use it.

// Get and Merge KeyValues
foreach ($partKeyValues as $partKeyValue) {

   $referenceId = $partKeyValue->getValue();
   $taskVersions = TaskVersionsRepository::getTaskVersionsByReferenceId($referenceId);

// Very radical concept in object oriented programming, may crash, yes it crashed.
class KeyValues extends IteratorIterator {

    public function __construct(KeyValues ...$keyValues)
        parent::__construct(new ArrayIterator($keyValues));

    public function count() : int
        return $this->getInnerIterator()->count();

    public function merge(KeyValues $keyValues)
        foreach ($keyValues as $keyValue) {

    public function uaSort(): KeyValues {
            function(KeyValue $a, KeyValue $b) {
                return $a->getValue() <=> $b->getValue();

class KeyValue {

    private $key;
    private $value;

    public function __construct()


    public function getKey() { return $this->key; }
    public function setKey($key) { $this->key = $key; }

    public function getValue() { return $this->value; }
    public function setValue($value) { $this->value = $value; }    


So your probably wondering what the story here is on me working with PHP 7.4. I decided to help this company that got burned on a PHP 4.7 project last worked on in 2011, in which the designers and coders lost control of proper programming practices, going completely crazy with PHP which is typical. They put the presentation HTML in classes, and business logic in the presentation layer. Then their IT guy thought he could be a programmer and started working on it making it worst, because he thought the existing code was proper programming practices.

Whats weird, is that the IT company hosting the App suggested to the customer that they should upgrade from PHP 4.73 to PHP 8 to plug the security holes, thinking that the upgrade was like upgrading to Windows 10. So I went along with it, and began to realize that upgrading to PHP 8 was more like a quest to stop writing bad procedural code and embrace the power of object orientated programming in PHP 8. My goal is to get this right, do a great job, and not shame myself with what I deliver.

I'm starting to like PHP, and see why so many organizations use it to this date. This really hasn't been a journey of learning how to code in PHP, but more like a proper lesson in how to implement proper design principles for me. Perhaps this finally elevates me to a higher level of thinking.
If it ain't broke don't fix it
