cookies help

[carlosa69]

I have searched and found a lot of problems more complicated than mine. Here is my question:
Can you read a cookie before you output to the browser?

I'm trying to make it so that my index.php has two buttons: flash or html. When flash is submitted, it sends the variable "$format" as "flash," and index.php will display the flash version. When a check box, "go here every time" on index.php is checked, a cookie will be set so that they don't have to click which one to go to every time. how do I do this?

Cookies are header information.
If a cookie is present on the clients terminal, the cookie will be sent with the HTTP_REQUEST header. And that of course means that yes, you can read a cookie before you do anything, since the cookie info will allready be present in the PHP auto globals BEFORE your code does anything.

If you want to read info from a cookie while setting it, well... just check the vars you are setting before you send it.

simple as that.
