note 89421 added to function.strtok

As of the change in strtok()'s handling of empty strings, it is now useless for scripts that rely on empty data to function. Take for instance, a standard header. (with UNIX newlines) http/1.0 200 OK\n Content-Type: text/html\n \n --HTML BODY HERE--- When parsing this with strtok, one would wait until it found an empty string to signal the end of the header. However, because strtok now skips empty segments, it is impossible to know when the header has ended. This should not be called `correct' behavior, it certainly is not. It has rendered strtok incapable of (properly) processing a very simple standard. This new functionality, however, does not affect Windows style headers. You would search for a line that only contains "\r" This, however, is not a justification for the change. ---- Server IP: 69.147.83.197 Probable Submitter: 24.102.58.146 (proxied: 127.0.0.1) ---- Manual Page -- http://www.php.net/manual/en/function.strtok.php Edit -- https://master.php.net/note/edit/89421 Del: integrated -- https://master.php.net/note/delete/89421/integrated Del: useless -- https://master.php.net/note/delete/89421/useless Del: bad code -- https://master.php.net/note/delete/89421/bad+code Del: spam -- https://master.php.net/note/delete/89421/spam Del: non-english -- https://master.php.net/note/delete/89421/non-english Del: in docs -- https://master.php.net/note/delete/89421/in+docs Del: other reasons-- https://master.php.net/note/delete/89421 Reject -- https://master.php.net/note/reject/89421 Search -- https://master.php.net/manage/user-notes.php
