note 75405 added to function.preg-replace

Heres a great script that I use for my search engine to make keywords appear bold but it can be used for other uses. <?php /* $keywords = Keywords to highlight $message = String to highlight the keywords in $stag = Starting HTML tag for the highlighted string $etag = Ending HTML tag for the highlighted string */ function do_highlight($keywords, $message, $stag = "<b>", $etag = "</b>"){ preg_match_all("/\"(.*?)\"/", $keywords, $quotes); foreach($quotes[1] as $quot){ $terms[] = $quot; } $keywords = preg_replace("/\".*?\"/", "", $keywords); $keywords = preg_replace("/\"/", "", $keywords); $keywords = preg_replace("/ /", " ", $keywords); $terms = array_merge($terms, explode(" ", $keywords)); foreach($terms as $term){ if(trim($term)){ $message = preg_replace('#(?<=[^\w=])('.$term.')(?=[^\w=])#siU', $stag.'\\1'.$etag, $message); } } return $message; } echo do_highlight('"steve miller band" airliner 1977 paul', "\"Jet Airliner\" is a song by the Steve Miller band released in 1977 the song was written by Paul Pena. The song describes a man who is looking for a new life so he sings how he can barely get on a \"Big ole' Jet Airliner\"."); ?> ---- Server IP: 69.39.81.135 Probable Submitter: 68.230.192.222 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- https://master.php.net/note/edit/75405 Del: integrated -- https://master.php.net/note/delete/75405/integrated Del: useless -- https://master.php.net/note/delete/75405/useless Del: bad code -- https://master.php.net/note/delete/75405/bad+code Del: spam -- https://master.php.net/note/delete/75405/spam Del: non-english -- https://master.php.net/note/delete/75405/non-english Del: in docs -- https://master.php.net/note/delete/75405/in+docs Del: other reasons-- https://master.php.net/note/delete/75405 Reject -- https://master.php.net/note/reject/75405 Search -- https://master.php.net/manage/user-notes.php
