Hi Merlin, Sounds like you need to use preg_replace, specifically testing for word boundaries. See http://au2.php.net/preg_replace and http://php.mirrors.ilisys.com.au/manual/en/reference.pcre.pattern.syntax.php for the \b word boundary syntax. Not tested, but something like the following would probably be along the right lines: $thing = preg_replace('/\bin\b/i','<b>in</b>','adventures in singapore'); echo $thing; produces: "adventures <b>in</b> singapore", ignoring the 'in' characters within 'singapore' because they don't form a word boundary Hope this helps, Much warmth, Murray -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
