I wasn't sure if you wanted to return a line from the text (which Dan seems
to have taken care of pretty well) or if you just wanted to replace words
with formatted versions of themselves.  Here's a really basic function I use
to do the latter with multiple keywords (sep. by spaces):

<?php
    function highlight($keywords, $text) {
        $keywords = trim($keywords);
        
        if (strlen($keywords)) {
            $keywords = explode(' ', $keywords);
            
            if (count($keywords)) {
                foreach($keywords as $keyword) {
		        // you could, of course use whatever html formatting
you want here
                    $text = preg_replace('/(' . $keyword . ')/i',
'<b>\\1</b>', $text); 
                }
            }
        }
            
        return $text;
    }
?>

Good Luck!
