Ahhh yes .... I have seen this mentioned somewhere, and yet I can't remember
where right now. This is the output buffering that lets you even put header
content after page content and still have it appear before, isn't it?
If I remember correctly, this is controlled by setup on the server, right? A
setting in the php.ini file that controls this? If so ... I may have to
plead with my web host, I don't actually own and run the server my site is
hosted on ... but definitely something I'll do some more reading on
I am pretty much a newbie, having taught myself what I need to know, and
I've done some major experimenting ... I haven't even gotten into some of
the more complex functions of PHP. I used to have my site primarily coded in
Javascript/DHTML, and I basically adopted what I was trying to do with DHTML
into Javascript if that tells you the complexity I'm currently working on.
I've only started playing with file functions, to say nothing of databases.
