find array in array by key, and set value

Question

So I have a function which loops through Objects recursive, cause some of Object have objects inside for example the object Person can contain object Adress and puts them into an array.

so basically this can be a structure from a model:

 [obj] Neededforexample
 - [obj] person
 -- [prop] first-name
 -- [obj] adress
 - SomeProperty

So the function which loops through it is completed:

private static function SetPropertiesArray($class,$parentClass = null){
    $object = new $class;
    $objectProperties = get_object_vars($object);
    foreach($objectProperties as $prop => $value){
        //echo $prop;
        if(class_exists($prop)){
            if($parentClass !== null){

                self::$_propertiesArray[$parentClass][$prop] = $value;
            }
            else{
                self::$_propertiesArray[$prop] = $value;
            }
            self::SetPropertiesArray($prop,$prop);
        }
        else{
            if($parentClass !== null){
                self::$_propertiesArray[$parentClass][$prop] = $value;
            }
            else{
                self::$_propertiesArray[$prop] = $value;
            }
        }
    }

    return self::$_propertiesArray;
}

This outputs this array:

"NeededForExample" => array(
  "Person" => null,
  "SomeProperty" => "Somevalue",
  "First-name" => "Firstname",
  "adress" => "HERE")

While I want:

"NeededForExample" => array(
  "Person" => array(
   "First-name" => "firstname",
   "adress" => array(
     "street" => "streetname"
   ) 
  ),
  "SomeProperty" => "Somevalue")

Could you post 1 or 2 elements in the original array containing your data/objects? This is so that we can see the Structure a bit.... You could do a var_dump() on your data and copy-paste the first 1 or 2 elements.... — Poiz

The line if(class_exists($prop)){; should it not read if(class_exists($class)){ ? Because $prop seems like the Property of the $class in question and not the Class itself... and get_object_vars returns an Array containing the properties of an Object... but not the Class itself.... — Poiz

@Poiz yeah you're right should be this works fine tho since every models class included needs an object in my case but what you just said is true. — Roy Stijsiger

Something was tried below... instead of using Recursive function, 2 functions were used instead... check it out & see how it plays out. You can check out the Demo here: eval.in/609466 — Poiz

The Code below may be pertinent to your case. But you may test it out here first.

    <?php

        $helper         = new Helper("Person", null);
        var_dump($helper->getPropertiesArray());



        class Helper{

            protected $Message;
            protected static $_propertiesArray = array();

            public function __construct($class, $parentClass) {
                self::SetPropertiesArray($class, $parentClass);
            }

            private static function SetPropertiesArray($class, $parentClass = null){
                $object             = new $class;
                $objectProperties   = get_object_vars($object);

                foreach($objectProperties as $prop => $value){
                    if(!is_null($parentClass)){
                        // CHECK IF $prop IS A CLASS...
                        if(class_exists($prop)){
                            self::$_propertiesArray[$parentClass][$class][$prop] = self::getClassPropertiesArray($prop, $parentClass);
                        }else{
                            self::$_propertiesArray[$parentClass][$class][$prop] = $value;
                        }
                    }else{
                        // CHECK IF $prop IS A CLASS...
                        if(class_exists($prop)){
                            self::$_propertiesArray[$class][$prop] = self::getClassPropertiesArray($prop, $parentClass);
                        }else{
                            self::$_propertiesArray[$class][$prop] = $value;
                        }

                    }
                }

                return self::$_propertiesArray;
            }

            private static function getClassPropertiesArray($class, $parentClass = null){
                $object             = new $class;
                $objectProperties   = get_object_vars($object);
                $arrClassProperties = array();

                foreach($objectProperties as $prop => $value){
                    $arrClassProperties[$prop] = $value;
                }
                return $arrClassProperties;
            }

            public function getPropertiesArray(){
                return self::$_propertiesArray;
            }
        }

        class Person{
            public $SurName  = "Test Surname";
            public $LastName = "BurgerServiceNummer" ;
            public $Address;
        }


        class Address{
            public $Street;
            public $ZipCode;
            public $City;
            public $Country;
        }

THE VAR_DUMP ABOVE PRODUCES::

        array (size=1)
          'Person' => 
            array (size=3)
              'SurName' => string 'Test Surname' (length=12)
              'LastName' => string 'BurgerServiceNummer' (length=19)
              'Address' => 
                array (size=4)
                  'Street' => null
                  'ZipCode' => null
                  'City' => null
                  'Country' => null

This is my solution

<?php
function SearchArrayForKeyAndAdd(&$array, $given_key, $name, $data = null){
    foreach($array as $key => &$value){
        if(is_array($value)){
            if($key == $given_key){
                $value[$name] = $data;
            }
            else{
                SearchArrayForKeyAndAdd($value,$given_key, $name, $data);
            }

        }
        else{
            if($key == $given_key){
                $value[$name] = $data;
            }
        }
    }
}
$array = array(
    "person" => array(
        "Name" => "Roy Stijsiger",
        "Adress" => null
    )
);


SearchArrayForKeyAndAdd($array,"Adress","Huisnummer",1);

SearchArrayForKeyAndAdd($array,"Adress","Straatnaam","Nortierstraat");
var_dump($array);

This was dummy code^^ This is the working code like I showed above VV

private static function SetPropertiesArray($class,$parentClass = null){
        $object = new $class;
        $objectProperties = get_object_vars($object);
        foreach($objectProperties as $prop => $value){
            //echo $prop;
            if(class_exists($prop)){
                if($parentClass !== null){
                    self::SearchArrayForKeyAndAdd(self::$_propertiesArray,$parentClass,$prop,$value);
                }
                else{
                    self::$_propertiesArray[$prop] = $value;
                }
                self::SetPropertiesArray($prop,$prop);
            }
            else{
                if($parentClass !== null){
                    self::SearchArrayForKeyAndAdd(self::$_propertiesArray,$parentClass,$prop,$value);
                }
                else{
                    self::$_propertiesArray[$prop] = $value;
                }
            }
        }

        return self::$_propertiesArray;
    }

    private static function SearchArrayForKeyAndAdd(&$array, $given_key, $name, $data = null){
    foreach($array as $key => &$value){
        if(is_array($value)){
            if($key == $given_key){
                $value[$name] = $data;
            }
            else{
                self::SearchArrayForKeyAndAdd($value,$given_key, $name, $data);
            }
        }
        else{
            if($key == $given_key){
                $value[$name] = $data;
            }
        }
    }
