[RESOLVED] weird error

jmack159

hey guys,

im getting this error on some, but not all, of my pages:
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\some_path\index.php:1) in c:\some_path\userspace\include\session.php on line 48

session.php is a session class that starts the session, authenticates users, and gathers user info from the db to populate class vars.

i have error_reporting() set to E_ALL. i get the error on all the pages, except two, in the root directory. in pages in daughter directories (like \userspace) the error message does not display.

all these pages have this as the first line in the file:

<?php
include 'session.php';
?>

with no other output before that. why am i getting errors on some pages and not others? what can i do to make these errors go away?

not sure if it makes a difference but im on WAMP.

what's line 48 and the one above of session.php ?

Well, the error message tells you right where the problem is:

output started at c:\some_path\index.php:1

So, open up index.php and look at the first line. Make sure nothing is outputted (including any blank spaces).

line 48 is:

session_start();

the line above that only declares a global var.

i do not have any output prior to that line, and it is typed exactly as in other pages that do not get errors. thats why this is confusing and frustrating.

Can you perhaps rename your index.php to index.txt and attach it to a post? It might be that you've saved it as a UTF-8 file and there's a BOM marker at the beginning.

Either way, there's something outputting data on the first line of index.php and that's where your problem is.

jmack159

here is index.txt

dagon

theres a char "ï»¿" being outputted before the <?php

jmack159

i cant see that in either dreamweaver or notepad. what are you using that you can see those characters?

dagon

just delete and retype the first line and you will be fine

dagon

if you open the file in notepad with encoding set to ansii you will see it, its a utf-8 encoded char so the others are showing it as is.

jmack159

no luck with that. the .txt is saved as ansii file, and i still cant see those characters in notepad.

thanks for all the help!

bradgrafelman

Try saving it as ANSI, completely erasing the first line, and retyping it.

jmack159

haha! success! thanks a lot!

bradgrafelman

In case you need to use UTF-8 encoding in the future, make sure you don't have a BOM marker. In Notepad2, I believe the solution would be to save it as UTF-8 without a signature (when I downloaded your .txt file, Notepad2 detected the format to be "UTF-8 with signature").

jmack159

cool, thanks for the tip.
