Using output buffering to modify the output

Question

Hi,

I want to make some custom changes to part of the output. Will be too complicated to do it by a plugin because there are many changes and as well, I need to directly overwrite some of the functions which can't be overwrited by a plugin.

My idea is to overwrite the output by using ob_start and ob_end_flush.

I see some occurences of ob_start in 1.5.2 code as well. Should be any interference if I add my own ob_start and ob_end_flush on index.php?

Answer 1

It should be fine, since PHP allows nesting of output buffering.
