UPDATE: Instead of using a foreach loop in stdClassHelper::__set_state() you can compress that code into a single line:

return (object) $array;

// This is an example of how you can use __set_state() with a stdClass object in PHP 5
$myStdClass = new stdClass();
$myStdClass->foo = 'bar';
echo '$myStdClass = ' . print_r($myStdClass, true) . "n";

// The below line outputs: stdClass::__set_state(array('foo' => 'bar',))
// Actually calling stdClass::__set_state() in PHP 5 will produce a fatal error.
echo 'var_export = ' . var_export($myStdClass, true) . "nn";

// Replace the text "stdClass::" with "stdClassHelper::" like so:
$myNewStdClass = stdClassHelper::__set_state(array('foo' => 'bar',));

// Success!
echo '$myNewStdClass = ' . print_r($myNewStdClass, true);

// Here's how it's done.
class stdClassHelper
{
public static function __set_state(array $array)
{
$stdClass = new stdClass();
foreach ($array as $key => $value)
{
$stdClass->$key = $value;
}
return $stdClass;
}
}
