u must be using header() function after ur output has started...
mind it header() cant be used once you started sending some output to ur browser.. not even a single blank space...

Post up the code if u need more clarification on this

As i said, u cant use header after sending output to browser(echo statements in this case)... Remove all echo statements before header or use them after it... though it wont get displayed in ur browser if u use them after header...
Cheers!

any of those headers are not working

[venkat0904]

yeah none will work... actually looking at your code i feel there is no need of those echo statements there... may i suggest u to remove all those echo statements. Any header after an echo statement wont work

any of those headers are not working

Not only echo, you will get this warning if you have session_start along with header function. Use

ob_start();

as the first line of your script to turn on output buffering and

ob_end_flush();

as the last line to flush the output to the buffer.
