Hi!May Be Ur Right My Friend...But When When I Got This Error:"Warning: Cannot modify header information - headers already sent by (output started at "I Just Use BUFFERING, And It Works Well Every time.Seriously I Don't Know! How & Why! But It works :S

That's like saying "when I feel sick, I take these GREEN PILLS, and I feel better. I don't know how they work, but they do. Every time!" :)More, perhaps, like surrounding your entire code in a try...catch block.The warning occurs because you are trying to send a header after the headers have already been sent. This is commonly caused by starting the transmission of the response body, as all headers need to be sent by that point. Output buffering delays the sending of the response body, and thus the error disappears. However, the issue is usually symptomatic and just making the error message go away, like you are doing, is unlikely to fix the underlying flaws in the code.

First, remove the output buffering code. There's a newline near the top of the file that gets sent as output that is almost definitely going to corrupt any file.Second, your memory limit is set too low, to only 8MB. You should raise that to 128MB. You can use ini_set at runtime to set the memory_limit option, but you can't set it to a higher value than what's in php.ini. Ask your host to increase the memory limit to 128MB in php.ini.http://www.php.net/manual/en/ini.core.php#ini.memory-limit
