How to convert an array to object in PHP?

In the simplest case, it's probably sufficient to "cast" the array as an object:

$object = (object) $array;

Another option would be to instantiate a standard class as a variable, and loop through your array while re-assigning the values:

$object = new stdClass();
foreach ($array as $key => $value)
{
    $object->$key = $value;
}

As Edson Medina pointed out, a really clean solution is to use the built-in json_ functions:

$object = json_decode(json_encode($array), FALSE);

This also (recursively) converts all of your sub arrays into objects, which you may or may not want. Unfortunately it has a 2-3x performance hit over the looping approach.

Warning! (thanks to Ultra for the comment):

json_decode on different enviroments converts UTF-8 data in different ways. I end up getting on of values '240.00' locally and '240' on production - massive dissaster. Morover if conversion fails string get's returned as NULL

you can simply use type casting to convert an array to object.

// *convert array to object* Array([id]=> 321313[username]=>shahbaz)
$object = (object) $array_name;

//now it is converted to object and you can access it.
echo $object->username;

The easy way would be

$object = (object)$array;

But that's not what you want. If you want objects you want to achieve something, but that's missing in this question. Using objects just for the reason of using objects makes no sense.
