note 105004 added to function.str-word-count

this is another version of algorithm for counting words, that uses all special chars from the first half of ascii table as delimiters. works quite good with utf-8: <?php function count_words($string) { //$string = htmlspecialchars_decode(strip_tags($string)); //optional if (strlen($string)==0) return 0; for ($i=0; $i<256; $i++) $d[$i] = (($i>0 && $i<=47) || ($i>=58 && $i<=64) || ($i>=91 && $i<=96) || ($i>=123 && $i<=127))? true:false; // delimiters from ascii table are set true $count= (!$d[ord($string[0])] || ord($string[0])>255) ? 1:0; for ($i=1; $i<strlen($string); $i++) { $cp= ord($string[$i-1]); $c = ord($string[$i]); $cp= ($cp>255 || $d[$cp]==false)? false:true; $c = ($c>255 || $d[$c]==false)? false:true; if ($cp && !$c) // if new word starts $count++; } return $count; } $str='skúška správnosti algoritmu'; echo count_words($str); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 80.87.209.10 ---- Manual Page -- http://www.php.net/manual/en/function.str-word-count.php Edit -- https://master.php.net/note/edit/105004 Del: integrated -- https://master.php.net/note/delete/105004/integrated Del: useless -- https://master.php.net/note/delete/105004/useless Del: bad code -- https://master.php.net/note/delete/105004/bad+code Del: spam -- https://master.php.net/note/delete/105004/spam Del: non-english -- https://master.php.net/note/delete/105004/non-english Del: in docs -- https://master.php.net/note/delete/105004/in+docs Del: other reasons-- https://master.php.net/note/delete/105004 Reject -- https://master.php.net/note/reject/105004 Search -- https://master.php.net/manage/user-notes.php
