Highlighting Search Keyword

[Anon]

Hello, I've been trying to figure out how I highlight the keyword of a simple search for a project I have been working on. With the following code, I can get the keyword highlighted, but I want the search results to come back in a style similar to Google, where the search result is chopped up just to show you the found keyword in various parts of a database article. Thanks for any help, or pointers!

function highlight( $needle, $haystack )
{
$parts = explode( strtolower($needle), strtolower($haystack) );

$pos = 0;

foreach( $parts as $key=>$part ){
    $parts[ $key ] = substr($haystack, $pos, strlen($part));
    $pos += strlen($part);

    $parts[ $key ] .= '<FONT COLOR="#ff0000"><B>'.substr($haystack, $pos, strlen($needle)).'</B></FONT>';
    $pos += strlen($needle);
   }

return( join( '', $parts ) );

}
