Not a question of how, but a question of why

I know this may sound impertinent, but that is not my intent at all, I'm just looking for a better understanding of what's going on. And this email is not meant to be a comparison either. But in ColdFusion I can call CFHEADER or CFCOOKIE from anywhere within my page, regardless of whether there has been output to the screen or not. This (the CFCOOKIE) part is tremendously helpful because you can do a series of processes, displaying status's, displaying tables, and then drop a cookie if so desired. Why do the Header() and SetCookie() function have to be before any output in PHP? Is it because CF is a two step process, parsing out the CFM, generating output, then passing it off to the web server to parse out the HTML and serve up? And PHP is a one step process?
