I?m using session variables to store objects and I?m having problems with different versions of PHP. Two files:-

//-------------
//start rjp.rqd
//-------------

<?
class test()
{
     function doEcho()
     {
          echo ?hello<BR>?;
     }
}
?>
//-----------
//end rqp.rqd
//-----------


//-------------
//start rjp.php
//-------------

<?
session_start();
session_register(?theTest?);
session_register(?Count?);
require (?rjp.rqd?);

$Count++;
if (!isset($theTest))
{
     $theTest = new test;
     echo ?test instantiated<BR>?;
}

$theTest->doEcho();
?>
You have visited this site <?echo $Count?> times<BR>
<A HREF=<?echo $PHP_SELF?>?<?=SID?>>page again</A>

<?
//-----------
//end rjp.php
//-----------
?>

This works fine on PHP version 4.0.1pl2 but gives the following error on PHP version 4.0.3pl1 (and 4.0.4pl1) when ?page again? is hit:-

Fatal error: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition test of the object you are trying to operate on was loaded _before_ the session was started in /testdir /rjp.php

I?ve cut the rqd file into the php file (so it?s actually part of the php file and not ?required?) and it works fine on both php versions.

register_vars, track_vars and enable_trans_sid are all enabled.

What am I doing wrong?

I would move the require line before the session_start() line.

So your code becomes:

require (?rjp.rqd?);
session_start();
session_register(?theTest?);
session_register(?Count?);

Ant,

I'll give that a try and see what happens.

I'll let you know how it goes.

Classes should be included before any other code if for anything other then readability.

session_register automatically issues a session_start so your use of session_start is redundant..

Thank a.marsh, that did the trick. Actually sorted it out at the weekend, but so busy didn't have time to respond. Thanks again.
