note 105488 added to function.similar-text

According to romain dot boyer at gmail dot com 08-Aug-2007 12:59: " Like levenchtein(), You can do : (strlen($string2) - similar_text($string,$string2)) to see how much characters have been changed. " Yes, but we have to remember about strings length - if first string is longer, we must substract from first length, if not, from second: <?php $string_first = 'Lorem ipsum'; $string_new = 'Lorem dolor'; $length_string_first = strlen($string_first); $length_string_new = strlen($string_new); if ($length_string_first > $length_string_new) { $changed_chars = ($length_string_first - similar_text($string_first, $string_new)); } else { $changed_chars = ($length_string_new - similar_text($string_first, $string_new)); } ?> ---- Server IP: 195.114.0.19 Probable Submitter: 83.4.113.81 ---- Manual Page -- http://www.php.net/manual/en/function.similar-text.php Edit -- https://master.php.net/note/edit/105488 Del: integrated -- https://master.php.net/note/delete/105488/integrated Del: useless -- https://master.php.net/note/delete/105488/useless Del: bad code -- https://master.php.net/note/delete/105488/bad+code Del: spam -- https://master.php.net/note/delete/105488/spam Del: non-english -- https://master.php.net/note/delete/105488/non-english Del: in docs -- https://master.php.net/note/delete/105488/in+docs Del: other reasons-- https://master.php.net/note/delete/105488 Reject -- https://master.php.net/note/reject/105488 Search -- https://master.php.net/manage/user-notes.php
