As mentioned above. An Autoloader implementation will repair this error.

The easiest workaround is to define my __autoload() function before session_start(). This way the appropriate classes are loaded when needed.

in my experience PHP sucks… it is not for programmers it is for children to play with…….

It’s just annoying.

Normally, you wind up with an __PHP_Incomplete_Class in $_SESSIONS when the *class* isn’t defined before calling session_start(), rather than when an object isn’t instantiated. The reason is PHP unserializes everything in the session storage; if a class isn’t defined, it unserializes it into a __PHP_Incomplete_Class.

I suspect the reason the fix worked was because you also first serialized the user, and thus unserialize it, probably after the class is defined. You’re getting the __PHP_Incomplete_Class error when accessing $_SESSION['user'], rather than in the script that performs the authentication, correct?

we can resolve this by giving a reference to the class which we are trying to unserialize.

class TwitterTweets
{
var $tweets;
var $image;
var $accName;
function __construct($tweet, $name, $image)
{
$this->tweets = $tweet;
$this->image = $image;
$this->accName = $name;
}
}
// if we are not having any reference we need to give a erference
// $tweetRaw['tweets'] – serialized class
$serTweetObj = unserialize($tweetRaw['tweets']);
