Re: Re: Strange PHP5 message

Hi, Jason, Thanks a lot for suggestion. Does it mean that I have tried to serialize some object (like adodb db object)? How I can eliminate this? I really cannot find where this object or whatever else is going to be serailized. The problematic line of code just serialized an array. On Mar 16, 2005, at 18:30, Jason Barnett wrote:

Notice: serialize() [function.serialize]: __sleep should return an array only containing the names of instance-variables to serialize. in ANVphpApp.php on line 840 Anyone knows what is the problem?

Exactly what the notice says ;) basically __sleep is used so that you can prevent certain properties (file pointers, db connections, objects, etc.) from being serialized. <?php session_start(); error_reporting(E_ALL); class Dummy {

  public    $s1  = 'I am a test string';

protected $s2 = 'I am the protected string'; private $_s3 = 'I am the private string';

  var       $a1  = array('testing', 1, 2, 3);
  static    $i1  = 0;

function __sleep() {

    $i = self::$i1++;
    echo "Oops, I forgot everything!  $i\n";
    return array();

} } class hasMemory extends Dummy { private $_fp = NULL; function __construct() {

    $this->_fp = fopen('/path/to/some/file', 'r');

} function __sleep() {

    $props_to_save = array('s1', 's2', 'a1');
    echo "I know about the following properties:\n";
    print_r($props_to_save);
    return $props_to_save;

} }

$_SESSION['obj1']    = new Dummy();
$_SESSION['obj2']    = new hasMemory();

$_SESSION['string'] = '123abcdefg!'; $_SESSION['integer'] = 1; $_SESSION['float'] = .1234; $_SESSION['double'] = .1234567890123456;

$_SESSION['bool']    = TRUE;

foreach ($_SESSION as $key => $value) { echo "$key: "; var_dump(serialize($value)); } ?> -- Teach a man to fish...
