Array_Fill() With Objects
+++++++++++++++++++++++++

  `array_fill() <https://www.php.net/array_fill>`_ fills an array with identical objects, not copies nor clones. This means that all the filled objects are a reference to the same object. Changing one of them will change any of them.

Make sure this is the intended effect in the code. 

This applies to `array_pad() <https://www.php.net/array_pad>`_ too. It doesn't apply to `array_fill_keys() <https://www.php.net/array_fill_keys>`_, as objects will be cast to a string before usage in this case. 



.. code-block:: php
   
   <?php
   
   $x = new StdClass();
   $array = array_fill(0, 10, $x);
   
   $array[3]->y = "Set in object #3";
   
   // displays "Set in object #3" 
   echo $array[5]->y;
   
   ?>
