Hi,
I have recently gone from using appache and PHP5 as a stand alone to using xampp and i have been developing a basic CMS to learn PHP. My CMS login system was working fine on Appache stand alone but when i try to use it on xampp i get this when i try to log in:

Warning: Cannot modify header information - headers already sent by (output started at D:\xampp\htdocs\TXT CMS\admin\login.php:6) in D:\xampp\htdocs\TXT CMS\admin\login.php on line 29

Line 29 is where it sets the cookie and line 6 is the <?php tag and i have no trouble when i upload it to my web server.

Another strange thing is that when i was trying to fix it i tryed to log in and after several attempts my computer blue screened and said something about cookies before it shut down, This might be unrelated but i just thought i would add it in.

I have searched already for a solution and i have tryed recreating the lang.tmp file and there is no output before the cookie is set.

I hope someone can shed some light on my problem and Thankyou in advance for your time and help.

Line 29 is where it sets the cookie and line 6 is the <?php tag and i have no trouble when i upload it to my web server.

Then you have some (HTML?) output before "<?php".

This is all there is above the <?php tag.

<html>
<head>
<title>Admin</title>
</head>
<body>

There is a html file included just after the <?php tag but i tryed removing this and it didnt help.

there must not be any output before a setcookie or "header(..." line.

But you can print those lines from the php part like so:

Code: Select all: <?php header('....'); //maybe more header('....'); echo '<html> <head> <title>Admin</title> </head> <body>'; //rest of the php part....

(or you have to use ob_start....., both methods are explained in php.net)

Thanks, That worked. How come it worked on my web server and on my stand alone apache but not XAMPP?

Ps. This isnt related but you might know. In a url what does %22 replace?

different setup.
Maybe "ob_start()...." in an autoprepend file or some such.
