In PHP is there any way (easily) to recursively replace an objects property w/ its contents?
ie: I want to remove the "data" property recursively down through this object. so its not a "middle man"
that way I don't have to call $foo->data->bar->data->id and I could just call $foo->bar->id
object(stdClass)[251]
public 'data' =>
object(stdClass)[224]
public 'id' => string '1730e209-0cbf-4598-8e5a-c5ca8469e8b9' (length=36)
public 'level_id' => string '12cada4e-0874-490e-adce-b58700244446' (length=36)
public 'level' =>
object(stdClass)[250]
public 'data' =>
object(stdClass)[252]
...
object(stdClass)[251]
public 'id' => string '1730e209-0cbf-4598-8e5a-c5ca8469e8b9' (length=36)
public 'level_id' => string '12cada4e-0874-490e-adce-b58700244446' (length=36)
public 'level' =>
object(stdClass)[250]
...
Is this what you want? I'm not sure, but, anyway...
foreach ($foo->data as $d){
$id = $d->bar->data->id;
... // do what you should here with $d children
}

I have big Object with protected properties and a property can be an array of other Objects. My goal is to print this entire Object as a single nested array. So I need to convert the object to an array.
I've tried doing:
$result = (array) $object;
But this converts only the highest lever object to an array and it messes up my protected properties names with weird question mark signs.
I've also tried something like this but this simply returns an empty array:
$result= json_decode(json_encode($object), true);
Here is what my object looks like:
object(Handling\Model\SearchBooking\Booking)[133]
protected 'jabooknr' => string '018024709' (length=9)
protected 'jitsbooknr' => string '' (length=9)
protected 'status' => string 'Y' (length=1)

EDIT
I have a method in my class where I "find" the result that looks like this:
public function findBooking()
{
//here happens a bunch of logic to get the right result
var_dump($object); exit; // this is the result that is show above
return $object;
}
There are a few issues, that make this difficult.
Property visibility, (private, protected) can cause issues when trying to read them outside of the class, proper. This is expected behavior as that's the point to not use public.
Classes are different. They are well defined and we know them ahead of time, but they are too diverse to account of all property names, at least not with a lot of wasted effort. Not to mention defining them "hard coding" would bite you later as it would make it difficult to maintain. For example if one of the packages does an update and you have coded the property names in you may have issues if they change them. On top of this given that these properties are not part of the classes Public "API" but instead part of the internals, it would not be unreasonable for them to change.
Properties can contain a mix of data types, including other classes or objects. This can make it challenging to handle.
Classes are part of other packages/frameworks and editing them is not practical, this restricts us to working outside of these classes.
So given these difficulties I would recommend using reflection to access the protected properties. Reflection allows you to inspect the definition of classes (and other stuff).
function jsonSerialize($obj){
return json_encode(toArray($obj));
}
function toArray($obj){
$R = new ReflectionObject($obj);
$proerties = $R->getProperties();
$data = [];
foreach($proerties as $k => $v){
$v->setAccessible(true);
$property = $v->getName();
$value = $v->getValue($obj);
if(!is_object($value)){
$data[$property] = $value;
}else if( is_a($obj,'\\DateTime')){
//if its a descendant of Datetime, get a formatted date.
// you can add other special case classes in this way
$data[$property] = $value->format('Y-m-d H:i:s');
}else{
$data[$property] = toArray($value); //call recursively
}
}
return $data;
}
So assume we have these classes
class foo{
private $bar; //private nested object
public function __construct(){
$this->bar = new bar();
}
}
class bar{
private $something = 'hello';
}
$obj = new foo;
echo jsonSerialize($obj);
See it in a sandbox here
Outputs:
{"bar":{"something":"hello"}}
Also of note is we have a special consideration for the DateTime class. Instead of getting all the properties of this we just want the date (probably) formatted in some standard way. So by using is_a() (I'm old school) we can tell if the Object $value has a given class as an ancestor of it. Then we just do our formatting.
There are probably a few special cases like this, so I wanted to mention how to handle them.
Though it is an old query, most answers are not easy to follow. So I tried to simplify the code for this specific question.
The cleaner way to get JSON objects is by implementing the JsonSerializable interface.
class Booking implements JsonSerializable
{
protected $jabooknr;
protected $platform;
//Other attributes ....
//Array of tronsport
protected $transports;
protected $extraLuggage;
public function jsonSerialize()
{
return [
'jabooknr'=> $this->jabooknr,
'platform'=> $this->platform,
'transports' => [json_encode($this->transports)
],
'$extraLuggage' => $this->extraLuggage
];
}
public function __construct($jabooknr, $platform){
$this->jabooknr = $jabooknr;
$this->platform = $platform;
$this->transports=[new Transport()];
}
}
class Transport implements JsonSerializable{
protected $carriercode;
protected $carriernumber;
//Array of Pax
protected $pax ;
public function jsonSerialize()
{
return [
'carriercode'=> $this->carriercode,
'carriernumber'=> $this->carriernumber
];
}
}
$booking = new Booking('018024709',25);
echo json_encode($booking);
Why are new entities instantiated with null for all values except the data in the json, why is the entity constructor not setting defaults - putting a die() in the constructor never gets executed.
Update:
Ok so digging into the code, when no managed entity is found, JMSS will use the doctrine instantiator class to create the entity - its sole job, to create entities without calling the constructor. Is there a reason for this? this is inside JMS\Serializer\Construction\UnserializeObjectConstructor
I've configured the object constructor to use the doctrine object constructor written by JMS, but the same issue happens with and without this.
jms_serializer.object_constructor:
alias: jms_serializer.doctrine_object_constructor
public: false
Existing entities are updated without trouble, however new entities are missing all constructor set defaults.
Under 'fields' element 0 is existing, element 1 is new.
array (size=3)
'id' => int 2
'name' => string 'Categories' (length=10)
'fields' =>
array (size=2)
0 =>
array (size=7)
'id' => int 49
'displayName' => string 'Car Branded' (length=11)
'type' => string 'checkboxlist' (length=12)
'required' => boolean false
'disabled' => boolean false
'name' => string 'h49' (length=3)
1 =>
array (size=3)
'type' => string 'email' (length=5)
'name' => string 'field3491' (length=9)
'displayName' => string 'Email' (length=5)
The entity looks like this after deserializing:
object(stdClass)[2000]
public '__CLASS__' => string 'AppBundle\Entity\FormElement' (length=28)
public 'id' => null
public 'label' => string 'Email' (length=5)
public 'type' => string 'email' (length=5)
public 'defaultValue' => null
public 'required' => null
public 'mappedField' => null
public 'garbageCollection' => null
public 'sortOrder' => null
public 'disabled' => null
public 'uuid' => null
public 'form' => null
public 'multiOptions' => null
public 'filters' => null
public 'submissions' => null
The entity constructor:
public function __construct()
{
$this->required = false;
$this->disabled = false;
$this->garbageCollection = false;
$this->sortOrder = 0;
$this->type = 'text';
}
And finally this is how im deserializing:
$serializer = $this->get('jms_serializer');
$entryForm = $serializer->deserialize($json_data, 'AppBundle\Entity\EntryForm', 'json');
The issue is the default ObjectConstructor uses Doctrine's Instantiator, which does not call the class' constructor. To solve this, you can create your own ObjectConstructor that just returns a new instance of the class.
Example:
<?php
namespace AppBundle\Serializer;
use JMS\Serializer\Construction\ObjectConstructorInterface;
use JMS\Serializer\DeserializationContext;
use JMS\Serializer\Metadata\ClassMetadata;
use JMS\Serializer\VisitorInterface;
class ObjectConstructor implements ObjectConstructorInterface
{
/**
* {#inheritdoc}
*/
public function construct(
VisitorInterface $visitor,
ClassMetadata $metadata,
$data,
array $type,
DeserializationContext $context
) {
$className = $metadata->name;
return new $className();
}
}
If you're using the bundle, just set jms_serializer.unserialize_object_constructor.class parameter to that new class. Otherwise in your builder, use the class as your object constructor.
What worked for me was simply adding this to the jms_serializer config:
jms_serializer:
object_constructors:
doctrine:
fallback_strategy: "fallback"
I am returning a value from a variable in my controller but it yields different results when I dd($roles) in my blade view.
public function index()
{
$users = $this->user->getAll(); //DBUserRepository
$roles = $this->user->getRoles($users)
return $roles;
}
Yields correct results
{
id: "1",
username: "Muzikman",

created_at: "2014-10-24 20:45:26",
updated_at: "2014-10-24 20:45:26",
}
]
However, when return $roles from controller to blade it yields different results.
public function index() { $users = $this->user->getAll(); $roles = $this->user->getRoles($users);
return View::view('admin.index', compact('users'))->withRoles($roles); }
Blade var dump {{ dd($roles) }} returns

Can someone explain what is going on here? Sending the same data object to blade from the controller with different array contents.
Here is the code from my interface:
public function getRoles($users)
{
foreach($users as $user){
$roles[] = \User::with('roles')->find($user->id);
}
return $roles;
}
dd($roles) will spit out the object itself, as see in the second set of output.
{{ $roles }} is going to spit out the object having been run through its toJson() function, resulting in your first set of output.
in this code
public function index()
{
$users = $this->user->getAll(); //DBUserRepository
$roles = $this->user->getRoles($users)
return $roles;
}
you did not dump it, you return the $roles, i think, when you return something and the content is "JSONable", laravel will set the appropriate header and convert the content to JSON. (found in Illuminate\Http\Response)
while the other one
{{ dd($roles) }}
it is same with
<?php var_dump($roles); ?>
which in PHP says that the said function displays structured information about one or more expressions that includes its type and value.
I am just curious. If you are just getting 'roles' column by ::with('roles') function. Why did other info come up in your dd() function result?
This is a really simple task, that has me absolutely stumped! I'm pulling back some JSON via CURL and PHP, and attempting to access the data from the below structure:
object(stdClass)[1]
public 'maxResults' => int 43
public 'resultList' =>
array (size=43)
0 =>
object(stdClass)[2]
public '#class' => string '' (length=64)
public 'id' => int
public 'version' => int 0
public 'dateCreated' => string '2014-02-11T18:37:55.835+0000' (length=28)
public 'dateModified' => null
public 'locationId' => int
public 'departmentId' => int
public 'ownerCompanyId' => int
public 'active' => boolean true
public 'userId' => int
public 'userName' => string '' (length=24)
public 'externalCode' => null
public 'employeeDetails' =>
object(stdClass)[3]
...
public 'chargeBandAllocationsIds' =>
array (size=7)
...
public 'personalRateChargeBandId' =>
object(stdClass)[13]
...
public 'employeeGroupIds' =>
array (size=0)
...
public 'isResource' => boolean false
(I've removed some of the values, for privacy reasons)
Now I'm trying to var_dump using var_dump(json_decode($result, false));, however when I try and get into the 'resultList' array using var_dump(json_decode($result['resultList'], false)); I get an illegal string offset error.
$result is the JSON string, your cannot do $result['resultList'] on a string. It only becomes a structure after you json_decode it. However, you're decoding it as object, not array, so this wouldn't work either way.
$data = json_decode($result);
var_dump($data->resultList);
var_dump($data->resultList[0]);
var_dump($data->resultList[0]->id);
foreach ($data->resultList as $employee) {
var_dump($employee->id);
}
Here is what is making my brain hurt. First, I know just enough php to explain it in about 5 minutes. I am however fairly versed in object oriented programming. The situation:
I am trying to build a php application to be used as an intranet only tool. My thought is to save the current user in the session. I created a PHP model of my database user table. In the code I am authenticating the user and if the user authenticates then I am creating a User object and saving it in the session. The problem is that the User object is created but all of the properties are null. I have researched on here and php net for some answers and have tried several things but the problem persists. I do not think it is php related, I absolutely think it is something I am doing wrong but just can't put a finger on it. Here is the relevant code sample from the login script. To get here the password must validate, the variable $users is the direct return from the function in my database controller. Since the variable is included in the var_dump the code returning that variable may not be needed. I have tried passing the relevant array elements separately to the constructor, I have tried passing the full array, I have used serialize and unserialize. I have tried to set them using $this->property = $someValue .
if ($hash) {
$current_user = new User($users);
$_SESSION['current_user'] = serialize($current_user);
$current_user = unserialize($_SESSION['current_user']);
var_dump(session_id());
var_dump($users);
var_dump($current_user);
var_dump($_SESSION['current_user']);
}
Here is my constructor:
class User {
public $userid;
public $fname;
public $lname;
public $email;
public $username;
public $function;
public $d_joined;
public $is_internal;
public $is_active;
function __costruct() {
$arguments = func_get_args();
if (!empty($arguments)) {
foreach ($arguments[0] as $key => $property) {
if ($property_exists($this, $key)) {
$this -> {$key} = $property;
}
}
}
}
I have tried _construct($args) and _construct(array($args)) and nothing. Here is the output of the var_dump() calls
string 'cgotecrpu7soqvepoimjo2s116' (length=26)
array (size=1)

So from what I can see, the initial array $users has the correct data. The User object is created in the variable $current_user . However, when I try to access an object property I get an error about accessing an object property from a non-object. It looks like the session variable is not an object, but the $current_user is, even though it has null properties. Can someone point me in the right direction? Thanks.
Your constructor looks wrong for the thing you want to do, I think you should do it this way :
/**
* Constructor set each public values with the ones passed from the passed array
* #param array $userDatas Array containing the user datas
*/
function __construct($userDatas) {
foreach($userDatas as $key => $value) {
if (property_exists($this, $key)) {
$this->$key = $value;
}
}
}
