[php] Array of PHP Objects

So I have been searching for a while and cannot find the answer to a simple question. Is it possible to have an array of objects in PHP? Such as:

$ar=array();    
$ar[]=$Obj1    
$ar[]=$obj2

For some reason I have not been able to find the answer anywhere. I assume it is possible but I just need to make sure.

Another intuitive solution could be:

class Post
{
    public $title;
    public $date;
}

$posts = array();

$posts[0] = new Post();
$posts[0]->title = 'post sample 1';
$posts[0]->date = '1/1/2021';

$posts[1] = new Post();
$posts[1]->title = 'post sample 2';
$posts[1]->date = '2/2/2021';

foreach ($posts as $post) {
  echo 'Post Title:' . $post->title . ' Post Date:' . $post->date . "\n";
}

Arrays can hold pointers so when I want an array of objects I do that.

$a = array();
$o = new Whatever_Class();
$a[] = &$o;
print_r($a);

This will show that the object is referenced and accessible through the array.

Although all the answers given are correct, in fact they do not completely answer the question which was about using the [] construct and more generally filling the array with objects.

A more relevant answer can be found in how to build arrays of objects in PHP without specifying an index number? which clearly shows how to solve the problem.

Yes.

$array[] = new stdClass;
$array[] = new stdClass;

print_r($array);

Results in:

Array
(
    [0] => stdClass Object
        (
        )

    [1] => stdClass Object
        (
        )

)

Yes, its possible to have array of objects in PHP.

class MyObject {
  private $property;

  public function  __construct($property) {
    $this->Property = $property;
  }
}
$ListOfObjects[] = new myObject(1); 
$ListOfObjects[] = new myObject(2); 
$ListOfObjects[] = new myObject(3); 
$ListOfObjects[] = new myObject(4); 

print "<pre>";
print_r($ListOfObjects);
print "</pre>";
