By far the easiest and correct way to instantiate an empty generic php object that you can then modify for whatever purpose you choose:
<?php $genericObject = new stdClass(); ?>
I had the most difficult time finding this, hopefully it will help someone else!
object
Nesne İlklendirme
Yeni bir nesne oluşturmak için (bir sınıfın bir örneğini oluşturmak için)
new deyimi kullanılır:
<?php
class kediler
{
function birŞeySöyle()
{
echo "Miyav.";
}
}
$kedi = new kediler;
$kedi->birŞeySöyle();
?>Çok daha ayrıntılı bilgiyi Sınıflar ve Nesneler faslında bulabilirsiniz.
object türüne dönüşüm
Eğer object türünde bir değer object türüne
dönüştürülürse bir değişiklik olmaz. Başka türde bir değer
object türüne dönüştürülürse yerleşik
stdClass sınıfının yeni bir örneği oluşturulmuş olur.
Eğer değer null ise yeni örnek boş olur. Bir dizi object
türüne dönüştürülürse dizi elemanlarının isimleri değerleriyle birlikte
nesnenin özellikleri haline gelirler. Bu durumda PHP 7.2.0 öncesinde, sayısal
anahtarların yinelenmedikçe erişilmez olacağını unutmayın.
<?php
$obj = (object) array('1' => 'foo');
var_dump(isset($obj->{'1'})); // PHP 7.2.0 ve sonrasında 'bool(true)'
// öncesinde 'bool(false)' basar
var_dump(key($obj)); // PHP 7.2.0 ve sonrasında 'string(1) "1"
// öncesinde 'int(1)' basar
?>
Herhangi bir başka değer için, scalar isimli bir üye
değişken, değeri içerecektir.
<?php
$nesne = (object) 'heyo';
echo $nesne->scalar; // çıktısı: 'heyo'
?>

In PHP 7 there are a few ways to create an empty object:
<?php
$obj1 = new \stdClass; // Instantiate stdClass object
$obj2 = new class{}; // Instantiate anonymous class
$obj3 = (object)[]; // Cast empty array to object
var_dump($obj1); // object(stdClass)#1 (0) {}
var_dump($obj2); // object(class@anonymous)#2 (0) {}
var_dump($obj3); // object(stdClass)#3 (0) {}
?>
$obj1 and $obj3 are the same type, but $obj1 !== $obj3. Also, all three will json_encode() to a simple JS object {}:
<?php
echo json_encode([
new \stdClass,
new class{},
(object)[],
]);
?>
Outputs: [{},{},{}]

As of PHP 5.4, we can create stdClass objects with some properties and values using the more beautiful form:
<?php
$object = (object) [
'propertyOne' => 'foo',
'propertyTwo' => 42,
];
?>

<!--Example shows how to convert array to stdClass Object and how to access its value for display -->
<?php
$num = array("Garha","sitamarhi","canada","patna"); //create an array
$obj = (object)$num; //change array to stdClass object
echo "<pre>";
print_r($obj); //stdClass Object created by casting of array
$newobj = new stdClass();//create a new
$newobj->name = "India";
$newobj->work = "Development";
$newobj->address="patna";
$new = (array)$newobj;//convert stdClass to array
echo "<pre>";
print_r($new); //print new object
##How deals with Associative Array
$test = [Details=>['name','roll number','college','mobile'],values=>['Naman Kumar','100790310868','Pune college','9988707202']];
$val = json_decode(json_encode($test),false);//convert array into stdClass object
echo "<pre>";
print_r($val);
echo ((is_array($val) == true ? 1 : 0 ) == 1 ? "array" : "not an array" )."</br>"; // check whether it is array or not
echo ((is_object($val) == true ? 1 : 0 ) == 1 ? "object" : "not an object" );//check whether it is object or not
?>

Here a new updated version of 'stdObject' class. It's very useful when extends to controller on MVC design pattern, user can create it's own class.
Hope it help you.
<?php
class stdObject {
public function __construct(array $arguments = array()) {
if (!empty($arguments)) {
foreach ($arguments as $property => $argument) {
$this->{$property} = $argument;
}
}
}
public function __call($method, $arguments) {
$arguments = array_merge(array("stdObject" => $this), $arguments); // Note: method argument 0 will always referred to the main class ($this).
if (isset($this->{$method}) && is_callable($this->{$method})) {
return call_user_func_array($this->{$method}, $arguments);
} else {
throw new Exception("Fatal error: Call to undefined method stdObject::{$method}()");
}
}
}
// Usage.
$obj = new stdObject();
$obj->name = "Nick";
$obj->surname = "Doe";
$obj->age = 20;
$obj->adresse = null;
$obj->getInfo = function($stdObject) { // $stdObject referred to this object (stdObject).
echo $stdObject->name . " " . $stdObject->surname . " have " . $stdObject->age . " yrs old. And live in " . $stdObject->adresse;
};
$func = "setAge";
$obj->{$func} = function($stdObject, $age) { // $age is the first parameter passed when calling this method.
$stdObject->age = $age;
};
$obj->setAge(24); // Parameter value 24 is passing to the $age argument in method 'setAge()'.
// Create dynamic method. Here i'm generating getter and setter dynimically
// Beware: Method name are case sensitive.
foreach ($obj as $func_name => $value) {
if (!$value instanceOf Closure) {
$obj->{"set" . ucfirst($func_name)} = function($stdObject, $value) use ($func_name) { // Note: you can also use keyword 'use' to bind parent variables.
$stdObject->{$func_name} = $value;
};
$obj->{"get" . ucfirst($func_name)} = function($stdObject) use ($func_name) { // Note: you can also use keyword 'use' to bind parent variables.
return $stdObject->{$func_name};
};
}
}
$obj->setName("John");
$obj->setAdresse("Boston");
$obj->getInfo();
?>

In response to harmor: if an array contains another array as a value, you can recursively convert all arrays with:
<?php
function arrayToObject( $array ){
foreach( $array as $key => $value ){
if( is_array( $value ) ) $array[ $key ] = arrayToObject( $value );
}
return (object) $array;
}
?>

Do you remember some JavaScript implementations?
// var timestamp = (new Date).getTime();
Now it's possible with PHP 5.4.*;
<?php
class Foo
{
public $a = "I'm a!";
public $b = "I'm b!";
public $c;
public function getB() {
return $this->b;
}
public function setC($c) {
$this->c = $c;
return $this;
}
public function getC() {
return $this->c;
}
}
print (new Foo)->a; // I'm a!
print (new Foo)->getB(); // I'm b!
?>
or
<?php
// $_GET["c"] = "I'm c!";
print (new Foo)
->setC($_GET["c"])
->getC(); // I'm c!
?>

You can create [recursive] objects with something like:
<?php
$literalObjectDeclared = (object) array(
'foo' => (object) array(
'bar' => 'baz',
'pax' => 'vax'
),
'moo' => 'ui'
);
print $literalObjectDeclared->foo->bar; // outputs "baz"!
?>
