Sorry, not sure, I've never actually had cause to use output buffering. You might want to ask the question specifically in a new thread. In fact: Please do, I'd be very interested to hear what the others think ;-) - -- Nick Wilson // www.explodingnet.com -BEGIN PGP SIGNATURE- Version: GnuPG v1.0.6 (GNU/Linux) iD8DBQE9ChHWHpvrrTa6L5oRAiucAJ9Zpydunune2hmPjaBvyMAE9GpYCQCfSJZy /2SzYVUDutkYu5821iyjscI= =rBgs -END PGP SIGNATURE- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] session variables in OOP....
If you want to do it right, don' t output anything, obviously. Instead of using ECHO, assign all output to a variable within your class. Then, at the end of the processing, after everything is done, echo out that variable (which will contain the entire page). Then you can set cookies, sessions, whatever, at any point. Or you can use output buffering... ---John Holmes... - Original Message - From: "Wilbert Enserink" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, June 14, 2002 7:44 AM Subject: [PHP] session variables in OOP Hi all, I'm busy building a site which uses OOP.

Re: [PHP] session variables in OOP....
Hi all,
Nick: thx for the tip, it removed the error, and might further be a good
idea: except:
do you know if I can declare session variables and use them in between the
output buffer statements
like this: (i tried it but it doesn't seem to work)??
greetings Wilbert
include ("class.basepage.php");
ob_start();//start the outputbuffering
$object= new basepage; //object basepage which determines which HTML
to output (due to queries and calcultaions)
session_register($variable);
$extra_variable=$variable+1;
echo "$extra_variable";
ob_get_contents();//show the buffer
ob_end_flush() ;//clear the buffer
