Actually, I do think it is somewhat internals related.

I want to know from the internals/experts angle if this is a good
function to be relying on, or if it is one of those things like the
"@" operator which I've been told is "expensive" and to me is one of
those things to stay away from.

Now if this breaks opcode caches like APC, I will have to find another way.

Also - I write procedural, not OOP. So that won't help here.

Would creating functions such as

output_foo_html()
output_foo_rss()
output_foo_json()

Then depending on the output, using something like this? Would this be
breaking opcode caches as well then?

if(function_exists('output_foo_'.$format)) {
    call_user_func('output_foo_'.$format);
} else {
    output_foo_html();
}
