Just out of curiosity, would it work if $needle, $str, $haystack had

Good point. You need to escape reserved regular expression characters in
$needle as follows:

if (!function_exists('str_ireplace')) {
function str_ireplace($needle, $str, $haystack) {
$needle = preg_quote($needle, '/');
return preg_replace("/$needle/i", $str, $haystack);
}
}

$str and $haystack do not need to be modified.

What if $str contained "\1"?
