Hi. The version 1.6.3 highlight fix to fix the version 1.6.2 highlight problem with exact words has a bug.

The bug is that with version 1.6.3, if you search on say 'php' using words begin or any words part, you will see something like 'blah blah phpdigHighlight">php' in the search results.

To fix this in version 1.6.3 do the following.

1. In robot_functions.php find:
   
   PHP Code:

   //replace any group of blank characters by an unique space
$text = ereg_replace("[[:blank:]]+"," ",eregi_replace("<[^>]*>","",$text)); 

   and right after add:
   
   PHP Code:

   //strip characters used in highlighting
$text = str_replace("^#_","",str_replace("_#^","",$text)); 

2. In phpdig_functions.php replace the phpdigHighlight function with the following:
   
   PHP Code:

   function phpdigHighlight($ereg='',$string='')
{
if ($ereg) {
//    return @eregi_replace($ereg,"\\\\1<span class=\"phpdigHighlight\">\\\\2</span>\\\\3",$string);
    $string = @eregi_replace($ereg,"\\\\1<^#_>\\\\2</_#^>\\\\3",@eregi_replace($ereg,"\\\\1<^#_>\\\\2</_#^>\\\\3",$string));
    $string = str_replace("^#_","span class=\"phpdigHighlight\"",str_replace("_#^","span",$string));
    return $string;
}
else {
    return $result;
}
} 

3. In search_function.php there are four places where the following occurs:
   
   PHP Code:

   phpdigHighlight($reg_strings,phpdigHighlight($reg_strings, 

   In these four places, remove the following from each line:
   
   PHP Code:

   // the first instance of phpdigHighlight($reg_strings,
// and also one ending ) to match parentheses 


Remember to remove any "word" wrapping in the above code.

EDIT: PhpDig version 1.6.4 includes this fix. See the Changelog for more details.
