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));
}
?>
