Both str_replace and preg_replace already support some array based
replacements, I think adding more options to these functions specifically
would just lead to confusion.
What you're proposing can already be achieved quite easily with
preg_replace_callback and passing your array/options into the anonymous
function with `use`, I'd personally welcome a str_replace_callback
counterpart.
