Th

Answer 1

str_replace(array(":))", ":)"), array("laugh.png", "smile.png"), $string);

The order is important.

Then

For :)) – (:\)\))

Answer 3

$string = str_replace(':))', 'laugh.png', $string);
$string = str_replace(':)', 'smile.png', $string);

php.net on str_replace: "If you don't need fancy replacing rules (like regular expressions), you should always use this function instead of ereg_replace() or preg_replace()."

Why don't you do a simple text replace?

First :)) to laungh.png, then :) to smile.png
