Walk though array applying my highlighting routine?

Hi List, I have worked out how to highlight all search words in a string. I hope its useful to some one. Please make it better if you can so we can all share it. But what I want to know is how can I treat each string with this highlighting routine individually so that my output is each string highlighted where necessary like the single string code dose below. So I turn $string into an array by $string[] for each three lines and tackle each one separately and when all search words are highlighted for that string do the next then the next and end up with 3 strings with each word in the string highlighted. Sorry for such a big post but I am trying to be as clear as possible to help others who may find this useful Thank you for any help or code adjustments Dave Carrera --- Current code below --- <?php $string = "Hello hello server site search me and highlight my words in search array words"; //$string = "Hello hello this is the second array elemaent to test server"; //$string = "this IS the third element of an array for words testing"; $string2 = "Hello hello server site search me and highlight my words in search array words"; $search = "hello array words"; //$string = trim($string); $search = trim($search); $words = explode(' ',$search); $words = array_unique($words); //$mysearchstring = strchr ($string,$far[0]); //$bold_find = substr($mysearchstring,0,$chars); for($i=0; $i<=count($words); $i++){ $word = preg_replace("/#/","\#",$words[$i]); $pregmatch = "#($word)(?![^<]*>)#i"; $pregreplace = "<b>$1</b>"; $h_string = preg_replace($pregmatch,$pregreplace,$string); $string = $h_string; } echo "Clean: $string2<br />"; echo "Criteria: $search<br />"; echo "HighLighted: $h_string<br />"; ?> --- Outgoing mail is certified Virus Free.
