Basically, I have a script that is included at the top of a page that does a bunch of things, the most important being an ob_start(). Then in the body of the page I have a variety of tags that will be replaced, such as {hello_word}. Then at the very end, I include another script that ends the output buffer, and makes the tag replacements with other code, then prints.
Is there any possible way to do this without having to include my second file at the end? Is there some simple way I can automatically execute a function or include a file at the very end?
You can register a function to be executed at the very end of script using
register_shutdown_function
