note 112015 added to function.ftok

The rather unintuitive usage of ftok with shm related functions like shmop_open and shm_attach could simply be explained as a need to avoid shm key collisions. Using ftok with a file that belongs to your project is likely to generate a unique key. Additionally, using ftok with a file from your project avoids the need to store the key so that other processes can access the segment because ftok will always give you the same key if you pass the same file. ---- Server IP: 69.147.83.199 Probable Submitter: 93.136.1.83 ---- Manual Page -- http://php.net/manual/en/function.ftok.php Edit -- https://master.php.net/note/edit/112015 Del: integrated -- https://master.php.net/note/delete/112015/integrated Del: useless -- https://master.php.net/note/delete/112015/useless Del: bad code -- https://master.php.net/note/delete/112015/bad+code Del: spam -- https://master.php.net/note/delete/112015/spam Del: non-english -- https://master.php.net/note/delete/112015/non-english Del: in docs -- https://master.php.net/note/delete/112015/in+docs Del: other reasons-- https://master.php.net/note/delete/112015 Reject -- https://master.php.net/note/reject/112015 Search -- https://master.php.net/manage/user-notes.php
