Headers

[fransm]

Does anyone know why I get the headers already sent fault when I output some content before I specify headers in one configuration of Apache and in another configuration I can output as mutch as I want and I will never get this warning. Is this a directive in Apache or is this something I have to set in php.ini?

That's the default configuration of PHP.

(Just read the PHP manual, chapter "header()". And in addition "output buffering".)
