note 112506 added to function.similar-text

To all those discussions about the speed problem of 'similar-text': My suggestion is to not use it in productive environments since strings can get very long very quickly (e.g. code versioning in TYPO3). The problem I see is, that the implementation of 'similar-text' is recursive and therefor it builds a huge callback-stack. This fails for two reasons: First building such a stack doesn't scale well (complexity of O(N**3) ) Secondly it simply crashes on long strings (mostly because of reason #1) It would be much better to reimplement 'similar-text' iteratively. ---- Server IP: 69.147.83.199 Probable Submitter: 212.23.141.251 ---- Manual Page -- http://php.net/manual/en/function.similar-text.php Edit -- https://master.php.net/note/edit/112506 Del: integrated -- https://master.php.net/note/delete/112506/integrated Del: useless -- https://master.php.net/note/delete/112506/useless Del: bad code -- https://master.php.net/note/delete/112506/bad+code Del: spam -- https://master.php.net/note/delete/112506/spam Del: non-english -- https://master.php.net/note/delete/112506/non-english Del: in docs -- https://master.php.net/note/delete/112506/in+docs Del: other reasons-- https://master.php.net/note/delete/112506 Reject -- https://master.php.net/note/reject/112506 Search -- https://master.php.net/manage/user-notes.php
