note 104478 added to function.uniqid

Prefix can be useful, for instance, if you generate identifiers simultaneously on several hosts that might happen to generate the identifier at the same microsecond. So we can include the hostname / servername in the id. <?php echo uniqid(php_uname('n'), true); // Output: darkstar4dfa8c27aea106.40781203 ?> ---- Server IP: 80.67.10.228 Probable Submitter: 85.228.18.85 ---- Manual Page -- http://www.php.net/manual/en/function.uniqid.php Edit -- https://master.php.net/note/edit/104478 Del: integrated -- https://master.php.net/note/delete/104478/integrated Del: useless -- https://master.php.net/note/delete/104478/useless Del: bad code -- https://master.php.net/note/delete/104478/bad+code Del: spam -- https://master.php.net/note/delete/104478/spam Del: non-english -- https://master.php.net/note/delete/104478/non-english Del: in docs -- https://master.php.net/note/delete/104478/in+docs Del: other reasons-- https://master.php.net/note/delete/104478 Reject -- https://master.php.net/note/reject/104478 Search -- https://master.php.net/manage/user-notes.php
