I've narrowed my problem a bit. As part of my framework, I set various
head variables (e.g. title, character-encoding, etc.) in an array
($HEAD) and then echo them by calling a function print_html_head($HEAD)
which returns the document declaration and head portion of my web page
as a string.
So far so good. But when I now echo this string, the page reloads
three times. To wit, breakpoint before echo statement, no reload.
After echo statement, page reloads three times. Note also: the output
is buffered, so it's not being output in the browser yet. And this is
the first echo statement in the script.
Anybody have any idea what this would be symptomatic of?
Thanks,
Tom
