Re: Extension for str_replace / preg_replace with arrays

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.
