note 75119 added to function.uniqid

In response to the notes about UUID generation added by mimec and lance_rushing at hotmail dot com. Calling mt_rand the fewest possible times is not necessarily the fastest, if it heavily utilizes string handling routines. I did a quick benchmark between the two functions and discovered that lance's function (using only 5 mt_rands) was about 6.5 times _slower_ than mimec's on my system. ---- Server IP: 80.81.171.181 Probable Submitter: 84.250.42.194 ---- Manual Page -- http://www.php.net/manual/en/function.uniqid.php Edit -- https://master.php.net/note/edit/75119 Del: integrated -- https://master.php.net/note/delete/75119/integrated Del: useless -- https://master.php.net/note/delete/75119/useless Del: bad code -- https://master.php.net/note/delete/75119/bad+code Del: spam -- https://master.php.net/note/delete/75119/spam Del: non-english -- https://master.php.net/note/delete/75119/non-english Del: in docs -- https://master.php.net/note/delete/75119/in+docs Del: other reasons-- https://master.php.net/note/delete/75119 Reject -- https://master.php.net/note/reject/75119 Search -- https://master.php.net/manage/user-notes.php
