note 125682 added to function.levenshtein

@Digeridoo $levenshtein = levenshtein($a, $b/*, 1, 1, 1*/); The easiest way (the one with minimum cost) to convert "1 apple" to "2 apples" is to replace "1" with "2" (at a cost of 1), and then insert an "s" (at a cost of 1). The total cost is therefore 2. $inserts = levenshtein($a, $b, 1, 0, 0); Again, we replace "1" with "2" and insert an 's'. The insertion has a cost of 1, and the replacement has a cost of 0; the total cost is 1. $deletes = levenshtein($a, $b, 0, 0, 1); Replacing "1" with "2" has zero cost, and so does inserting an "s"; the total cost of converting "1 apple" to "2 apples" is 0. $replaces = levenshtein($a, $b, 0, 1, 0); Easiest thing to do here is just delete everything and insert all-new text. Both have zero cost, so the total cost is 0. ---- Server IP: 45.112.84.4 Probable Submitter: 101.0.109.162 (proxied: 125.239.154.159) ---- Manual Page -- http://php.net/manual/en/function.levenshtein.php Edit -- https://master.php.net/note/edit/125682 Del: integrated -- https://master.php.net/note/delete/125682/integrated Del: useless -- https://master.php.net/note/delete/125682/useless Del: bad code -- https://master.php.net/note/delete/125682/bad+code Del: spam -- https://master.php.net/note/delete/125682/spam Del: non-english -- https://master.php.net/note/delete/125682/non-english Del: in docs -- https://master.php.net/note/delete/125682/in+docs Del: other reasons-- https://master.php.net/note/delete/125682 Reject -- https://master.php.net/note/reject/125682 Search -- https://master.php.net/manage/user-notes.php
