The piece of code you have submitted (see under) is interesting,
although there is one thing I don't find meaning to, even after RTFM,
and STFG(Searching The Funky Google). In your regular expression
pattern '#<b>.*</b>#Uis', what does this do : #...#Uis
Thank you very much
Piece of code :

<?php
$str = 'This X and this X will not be fixed, but <b>this X
and</b> and hopefully this <b>X</b> should be, along <b> with
this X also. </b>, but not this X.';
function myreplace($match)
{
$from = 'X';
$to = 'Y';
return str_replace($from,$to,$match[0]);
}
$new_str = preg_replace_callback('#<b>.*</b>#Uis','myreplace',$str);
echo $new_str;
?>
