Description:
------------
PDOStatement::fetchObject calls constructor after populating fields, which is not what I expected.

I expected it to call __construct() first, then populate fields.

Reproduce code:
---------------
<?php
	/* Test case for PDOStatement::fetchObject('ClassName')
	 * Vars populated before constructor is run.
	 */
	
	$db = new PDO("sqlite::memory:");
	$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
	
	$db->exec("CREATE TABLE person (id INTEGER NOT NULL, name varchar(100))");
	$db->exec("INSERT INTO person(id, name) VALUES (1, 'Fred')");
	
	class Person {
		var $id;
		var $name;
		function __construct() {
			$this->id = -1;
		}
	}
	
	$st = $db->query('SELECT * FROM person');
	$fred = $st->fetchObject('Person');
	
	print_r($fred);
?>


Expected result:
----------------
$fred->id should be 1

As the constructor will be called before variable population.

Actual result:
--------------
$fred->id is -1

Because the constructor is called after variable population.
