Problem with perg_replace

[BIOSTALL]

Hey 🙂 i have the following code:

if ($_GET['search']!="") {
	   		$getwords = explode(" ", $_GET['search']);
			$countgetwords = count($getwords);
			for ($i=0; $i<$countgetwords; $i++) {
				$message = preg_replace("/$getwords[$i]/i", " <span class='highlight'>$getwords[$i]</span> ", $message); 
			}
	   }

Basically its highlighting words that have been searched for. The trouble is if i search for 'and' and there is a 'handy' written in the text... it will highlight the 'and' within the 'handy' if that makes sense, lol... I only want it to highlight the word 'and'. Can someone please suggest how i can make this possible??

Many Thanks, BIOSTALL

use /\b{$getwords[$i]\b/i the \b indicates a word boundary

Nice one :-D Thanks

yeah~~~~~
now i know \b--->boundary,
what is \i then?

\i is nothing, if you are talking about the i after the delimeter ( / in this case ) it tells the engine to do a case insenstive match.
