I want to replace 'title' words to 'post_title' but ignore the 'post_title' words which already exist, so it do not become 'post_post_title', or any 'someword_title'. Just 'title'. Period.
I've tried with:
/[a-z_]?title/i
But it doesn't work

1Try `/(?<!_)title/i` or just `/\btitle\b/i` (to replace `title` as a whole word). – Wiktor Stribiżew Feb 02 '17 at 10:39
