serialize an object for a session fails.

[Anon]

hello, i\'ve got a problem with objects in a session variable.
here\'s the code, who isn\'t work...

class abc {
var $index=0;
var $hallo=2;

function getindex() {
return $index;
}
};

session_start();
session_register(\"SESSION\");

if (!isset($SESSION)) {
$SESSION = array();
}
if (!isset($SESSION[\"abc\"])) {
$SESSION[\"abc\"] = new abc;
}

/ ***************************** /
echo $SESSION[\"abc\"]->getindex();

... this function calls an errormessage like this:
Fatal error: The script tried to execute a method or access a property of an incomplete object.
Please ensure that the class definition abc of the object you are trying to operate on
was loaded before the session was started in d:\apache\htdocs\session.php on line 26<br>

when i only write simple variables into the session, i haven\'t any errors, but with objects. can you help me?
i\'ve got running php 4.0.5 on my computer.
thanx,trjo

Make sure that in your ini file that you have session.auto_start to 0
or else your session will start on the beging of the script

the problem also lies within the class definition. getindex has scope problems:

function getindex() {
return $index;
}

$index, scopewise, is a local variable to this function in this case, since $index isn't given any value in this scope, it returns nothing. If you are trying to refer to the object's $index property from within the object, it is written like this:

class abc {
var $index=0;
var $hallo=2;

function getindex() {
return $this->index;
}
};

Then you will get a 0. Also, it sounds like what Brad is saying looks like the beginning of your problem.
