ok so I love cookies and all but these cookies never turn out right...

PHP Code:


			
setcookie("active", "yes", time()+2592000);
setcookie("username", $_POST['username'], time()+2592000);

I always get an error that the headers were already sent and so these cookies don't get saved

I just decided to use $_SESSION instead...

Your problem is staying in IE only, is not right? If that's true, you can place

PHP Code:


			
header("P3P: CP='NOI ADM DEV PSAi COM NAV OUR OTRo STP IND DEM'");

before setcookie

I have been got headache with setcookie, but when I place header("P3P..."), evthing's ok.

A cookie is passed in the page header.
This means that if any characters are outputed before, a cookie cannot be set.
You must set your cookies before you sent/echo any character to the browser.
And this include even a space, or carriage return, put before your php block.
http://www.php.net/manual/en/function.setcookie.php

Quote:

Like other headers, cookies must be sent before any output from your script (this is a protocol restriction). This requires that you place calls to this function prior to any output, including <html> and <head> tags as well as any whitespace.

Not really helpful but can i just ask why dont they make PHP so while its parsing the script it kind of "collects" any headers or header output through out the script, and then send that then what ever othe rout put the script makes?

Er...
Dan, the output buffering functions are primarily designed for this...

http://www.php.net/manual/en/ref.outcontrol.php

Quote:

The Output Control functions allow you to control when output is sent from the script. This can be useful in several different situations, especially if you need to send headers to the browser after your script has began outputting data. The Output Control functions do not affect headers sent using header() or setcookie(), only functions such as echo() and data between blocks of PHP code.

no i mean like automartically by the PHP parser.

**tripy** · 02-09-2008, 12:45 PM

well, different applications calls for choices.
They choosed to not force it's usage, and it makes sense to me, as any call to a function have a cost (I mean, ram, cpu and processing time).
