How to bold the search term word in search ouput

I am using the following query for searching for songname and i want make the entered search term bold not the whole song name. For example if search for song name that starts with love i want the the output look like this :


power of love

write now it display the whole song name without bolding the search term .Could any one show me how that can be then.Thanks


<b><?=strval( $row['songname'] );?></b> ===> display songname

PHP Code:

---

$query  = "select id,artist,album,songname from musictest where songname like '%$s%'";
 
<td><? echo $numbers; ?>&nbsp;</td>
        <td><a href="javascript:newWindow('./playlistfromdbtotextfile.php?songid=<?=strval( $row['id'] );?>')"><img
        src="./images/Speaker.gif" alt="Listen to this Song"
        border="0" width="16" height="16"
        longdesc="Listen to this Song"></a> <b><?=strval( $row['songname'] );?></b>&nbsp;</td>
        <td><a
        href=" ./albumsongs.php?albumname=<?=strval( $row['album'] );?>&artistname=<?=strval( $row['artist'] );?>"><?=strval( $row['album'] );?></a>&nbsp;
        </td>
        <td><a
        href="albums.php?albumname=<?=strval( $row['artist'] );?>"><?=strval( $row['artist'] );?></a> </td>
        
    </tr>

use str_replace() to replace the search time in the song name with the added <b></b> tags around it
