foreach($word as $one)

{

while(preg_match('/b'.$one.'b/imU',$out,$match))

{

$out=str_replace($match[1],''.$match[1].'',$out);

}

raxtu no galvas+droši vien nostripsleshosies dazhi slashi, tāpēc 90% garantēts ka šitais koda klunķis tev ieciklēsies uz bezgalību ;-)

This is Google Hilite 0.3

by Dean Allen
http://textism.com 

When applied to a page arrived at via Google, this function will 
highlight the terms in the Google search wherever they appear. 
This is done through a CSS class.

How to use:

1. Save this file as 'google_hilite.php' somewhere on your server.

2. Add a style to your CSS:

.hilite { background-color: #FF9; }

(By all means change the colour, but the class must be called .hilite)

3. Place this at the top of your pages or template:

<?php 
$dr = $_SERVER[DOCUMENT_ROOT];
include_once($dr.'/PATH/TO/google_hilite.php');
ob_start("google_hilite"); 
?>

Place the following wherever you'd like to welcome the google visitor:

<? google_welcome(); ?>
