Why am I getting a session_start header problem?

[Eggzorcist]

My session start is in my session object and I include it at the top of my page prior my html code, yet I still get this warning:

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /Users/Sites/writepaps/index.php:2) in /Users/Sites/writepaps/includes/functions/sessions.php on line 11

 

I include the object in index line 2. and line 11 is where my session start is in my construct function

<?php
require_once("database.php");
require_once("user.php");

class Sessions {
public $logged_in = false;
protected $username;
protected $password;

function __construct(){
	session_start();
	$this->check_login();
} ....

 

 

Why is this happening?

Something has already been sent to the browser - even if this is just a space this will cause the page headers to be sent.

 

Move the session_start() to the very start of the script.

so I can't put it in the __construct of my function even if its included at the very top?

No. You just can't have any whitespace before [m[session_start[/m] outside of the <?php ?> tags. I'm guessing you have a newline or two before you open your PHP tags.

output started at /Users/Sites/writepaps/index.php:2 (line 2)

 

^^^ It would take seeing lines 1 - 2 of index.php to determine what output you are sending that is preventing the session_start() from working.
