What I want

Hi! I want to replace :) to smile.png and :)) to laugh.png.

The problem

The script finds :) inside :)) so laugh.png is not shown, only smile.png+)

This is what I have tried so far for :)):

preg_replace("/:)+(?!))/i",$image, $string))

Some other regexes what I tried:

"/\:\)+(?=\))/i"

"/\:+(?=\)\))/i"

But nothing want's to work what I tried yet.

Answer 1

For :) – (:\)(?!\)))

Then

For :)) – (:\)\))
