Bad idea. Very bad idea.
for example ( using bold to highlight ):
<?pseudo_code
$html = "<html><body>I want to hightlight the word body in this text.
</body></html>";
$search = "body";
$output = str_replace($search, "<b>$search</b>", $html);
// $output == "<html><<b>body</b>>I want to hightlight the word
<b>body</b> in this text. </<b>body</b>></html>";
// see what I mean?
