PHP WARNING:

Warning: session_start() [function.session-start]:Cannot send session cookie - headers already sent by
Warning: session_start() [function.session-start]:Cannot send session cookie - headers already sent by
Explanation:
This problem is normally cause because an html code was placed above the header. You need to be careful on that. header must be parse BEFORE html code.
Definiton:
The header() function sends a raw HTTP header to a client.
It is important to notice that header() must be called before any actual output is sent (In PHP 4 and later, you can use output buffering to solve this problem): for more... w3schools.com
<html>
<?php
// This results in an error.
// The output above is before the header() call
header('Location: http://www.example.com/');
?>
<?php
// This results in an error.
// The output above is before the header() call
header('Location: http://www.example.com/');
?>
Solution1:
ALWAYS MAKE SURE THAT session_start() is in the first line.
Solution2:ALWAYS MAKE SURE THAT session_start() is in the first line.
1 <?php
2 session_start();
3 ..................
4 ..................
5 ..................
6 ?>
You can place this line into your code.
// place this at the top of your page : ob_start() stored the output in the buffer
<? ob_start(); ?>
// place this at bottom of you page : ob_flush() flush the buffer
<?ob_flush();?>
Thank You, Hope this was helpful
