Description:
------------
when using custom object return through mysql_fetch_object, function allocates specified in second parameter object, sets up all properties and then calls constructor. I think this is wrong. Newly instantiated object's constructor must be called before any other operation on the object is performed.

Reproduce code:
---------------
/**
 * Object class
 *
 */
class Object {
  
  /**
   * Array of properties
   *
   * @var array
   */
  protected $_props =array();
  
  /**
   * Construct object
   *
   * @param array $props
   */
  public function __construct( $props =array()) {
    var_dump( 'constr');
    $this->_props =$props;
  }
  
  /**
   * Magic method override
   *
   * @param string $key
   */
  public function __isset( $key) {
    var_dump( 'isset');
    return array_key_exists( $key, $this->_props);
  }
  
  /**
   * Magic method override
   *
   * @param string $key
   * @return mixed/null
   */
  public function __get( $key) {
    var_dump( 'get');
    if( !array_key_exists( $key, $this->_props))
      return null;// entry does not exist
    // return obtained value
    return $this->_props[ $key];
  }
  
  /**
   * Magic method override
   *
   * @param string $key
   * @param mixed $value
   */
  public function __set( $key, $value) {
    var_dump( 'set');
    $this->_props[ $key] =$value;
  }
  
  /**
   * Magic method override
   *
   * @param string $key
   */
  public function __unset( $key) {
    var_dump( 'unset');
    unset( $this->_props[ $key]);
  }
  
  /**
   * Get associated array
   *
   * @return array
   */
  public function __invoke() {
    var_dump( 'invoke');
    return $this->_props;
  }
  
  /**
   * Get object name
   *
   * @return string
   */
  public function __toString() {
    return __CLASS__;
  }
  
}

......
mysql_fetch_object( $result, 'Object');

Expected result:
----------------
string(6) "constr"
string(3) "set"
string(3) "set"
string(3) "set"
string(3) "set"


Actual result:
--------------
string(3) "set"
string(3) "set"
string(3) "set"
string(3) "set"
string(6) "constr"
