highlighting text

[IxxI]

Does anybody know how to highlight text that relates to a search keyword that has been entered? As in if I searched for "does" in this question then the first word would be highlighted.
Thanks

Can we do that using PHP ?
I have following script , which searches file for a keyword(Search String) , If it is there it
will store the filename. Finally list of files which are stored in an array displayed using an array.
BUT the thing is : while displaying search results
we need to display the file name + some content of file in which key words should be highlighted.
Can we do like that ???


$data=fread(fopen("somefile","r"),filesize("somefile"));
if(eregi("$keyword",$data))
{
$array[]="somefile";
}
