I think I found a bug with setValue from ReflectionProperty - php

Question

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.
