I'm working on a function to recursively remove arrays and objects recursively. The problem is that certain recursions may be inside private properties of objects.

below is what I tried as well as the entries I tried to use.

this is my entrie

class TestOBJ

 private $fooClosure = null;
 public $bar = 5;
 private $myPrivateRecursion = null;
 private $aimArrayAndContainsRecursion = [];

 public function __construct()
 
 $this->fooClosure = function()
 echo 'pretty closure';
 ;
 

 public function setMyPrivateRecursion(&$obj)
 $this->myPrivateRecursion = &$obj;
 

 public function setObjInsideArray(&$obj)
 $this->aimArrayAndContainsRecursion[] = &$obj;
 


$std = new stdClass();
$std->std = 'any str';
$std->obj = new stdClass();
$std->obj->other = &$std;

$obj = new TestOBJ();
$obj->bar = new TestOBJ();
$obj->bar->bar = 'hey brow, please works';
$obj->bar->setMyPrivateRecursion($std);

my entrie is var $obj

and this is my function / solution

function makeRecursionStack($vector, &$stack = [], $from = null)

 if ($vector) 
 if (is_object($vector) && !in_array($vector, $stack, true) && !is_callable($vector)) 
 $stack[] = &$vector;
 if (get_class($vector) === 'stdClass') 
 foreach ($vector as $key => $value) 
 if (in_array($vector->$key, $stack, true)) 
 $vector->$key = null;
 else 
 $vector->$key = $this->makeRecursionStack($vector->$key, $stack, $key);
 
 
 return $vector;
 else 
 $object = new ReflectionObject($vector);
 $reflection = new ReflectionClass($vector);
 $properties = $reflection->getProperties();
 if ($properties) 
 foreach ($properties as $property) 
 $property = $object->getProperty($property->getName());
 $property->setAccessible(true);
 if (!is_callable($property->getValue($vector))) 
 $private = false;
 if ($property->isPrivate()) 
 $property->setAccessible(true);
 $private = true;
 

 if (in_array($property->getValue($vector), $stack, true)) 
 $property->setValue($vector, null);
 else 
 //if($property->getName() === 'myPrivateRecursion' && $from === 'bar')
 //$get = $property->getValue($vector);
 //$set = $this->makeRecursionStack($get, $stack, $property->getName()); 
 //$property->setValue($vector, $set);
 //pre_clear_buffer_die($property->getValue($vector));
 //
 $property->setValue($vector, $this->makeRecursionStack($property->getValue($vector), $stack, $property->getName()));
 

 if ($private) 
 $property->setAccessible(false);
 
 
 
 
 return $vector;
 
 else if (is_array($vector)) 
 $nvector = [];
 foreach ($vector as $key => $value) 
 $nvector[$key] = $this->makeRecursionStack($value, $stack, $key);
 
 return $nvector;
 else 
 if (is_object($vector) && !is_callable($vector)) 
 return null;
 
 
 
 return $vector;

The place where I have comments is where I noticed the problem. if the If is not commented there $get would receive a stdClass that has recursion and this works perfectly and $set would receive the stdClass without recursion. In that order.

$get =

$set =

After this lines

$property->setValue($vector, $set);
pre_clear_buffer_die($property->getValue($vector));

i obtain this

I try to put other value like an bool or null inside property and after set the $set but it's not works.

P.S: pre_clear_buffer_die kill php buffer, init other buffer and show var inside a <pre> after exit from script. Is an debugger function.
