PHP Error :

[anuj_web]

Hi

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/anujweb/public_html/Check.php:3) in /home/anujweb/public_html/Check.php on line 7

why does this error occur..this does not come up when run the page on localhost using apchetriad.....


How to remove it ??

thanks

session_start() MUST be the first thing to output (like with cookies) if any output has occured before that command, you'll get that error.

EDIT: watch your first line!

<?php

sends already output!

ok...thanks i'll keep that in mind
but session_start is a php command
how can it begin before <?php ??

I didn't say that, but it has to be the first thing to send output
like:

<?php
session_start();

is right

<?php
session_start();

gives that error

<?php
echo "text";
session_start();

= error

EDIT: send output, not execute
like this:

<?php
$var = "something";
//do a lot of stuff that does not output anything
session_start();

 

[anuj_web]

got it
