note 117201 added to function.uniqid

DUPLICATE UID WARNING: Be aware that calling this function many times in a tight loop (for instance, to assign UIDs to objects in an array) can result in many of the UIDs being identical, since less than a microsecond may have passed since the previous call. One simple solution is to compare the latest value returned with the previous result, and keep calling in a loop until the new value is different, if you don't mind this call causing a delay of 1 microsecond per call when necessary. ---- Server IP: 72.52.91.14 Probable Submitter: 192.231.86.253 ---- Manual Page -- http://php.net/manual/en/function.uniqid.php Edit -- https://master.php.net/note/edit/117201 Del: integrated -- https://master.php.net/note/delete/117201/integrated Del: useless -- https://master.php.net/note/delete/117201/useless Del: bad code -- https://master.php.net/note/delete/117201/bad+code Del: spam -- https://master.php.net/note/delete/117201/spam Del: non-english -- https://master.php.net/note/delete/117201/non-english Del: in docs -- https://master.php.net/note/delete/117201/in+docs Del: other reasons-- https://master.php.net/note/delete/117201 Reject -- https://master.php.net/note/reject/117201 Search -- https://master.php.net/manage/user-notes.php
