Thanks for the example, Thiago. This raises another question, however.
I noticed that the code below sends the header after the HTML tag, which
(if I understand correctly) requires a special setting in the php.ini
file. Assuming I don't have access to that file, is there a way to work
around this or to toggle that setting on a page-by-page basis?
Thanks.
