For shared memory needs, these functions are greatly outdated and inefficient. They don't provide read/write locking and they use a single linked list for storing the variables, which means they have an average complexity of O(n/2) where n is the number of variables in the segment. For a better alternative use APC Functions which implement proper read/write locking and use a hash table so they have good efficiency even for large amounts of variables: http://php.net/manual/en/ref.apc.php ---- Server IP: 72.52.91.14 Probable Submitter: 201.187.75.218 ---- Manual Page -- http://php.net/manual/en/ref.sem.php Edit -- https://master.php.net/note/edit/115292 Del: integrated -- https://master.php.net/note/delete/115292/integrated Del: useless -- https://master.php.net/note/delete/115292/useless Del: bad code -- https://master.php.net/note/delete/115292/bad+code Del: spam -- https://master.php.net/note/delete/115292/spam Del: non-english -- https://master.php.net/note/delete/115292/non-english Del: in docs -- https://master.php.net/note/delete/115292/in+docs Del: other reasons-- https://master.php.net/note/delete/115292 Reject -- https://master.php.net/note/reject/115292 Search -- https://master.php.net/manage/user-notes.php
