note 113221 added to function.mt-rand

/dev/urandom provides high entropy, but it is important to remember that it is created by collecting random os garbage from memory - if not enough of that garbage is created reading the file will just block the whole process until there is enough entropy to generate the requested random bytes. in debian-based setups, the rng-tools package can be used to manage entropy. ---- Server IP: 69.147.83.199 Probable Submitter: 213.196.195.73 ---- Manual Page -- http://php.net/manual/en/function.mt-rand.php Edit -- https://master.php.net/note/edit/113221 Del: integrated -- https://master.php.net/note/delete/113221/integrated Del: useless -- https://master.php.net/note/delete/113221/useless Del: bad code -- https://master.php.net/note/delete/113221/bad+code Del: spam -- https://master.php.net/note/delete/113221/spam Del: non-english -- https://master.php.net/note/delete/113221/non-english Del: in docs -- https://master.php.net/note/delete/113221/in+docs Del: other reasons-- https://master.php.net/note/delete/113221 Reject -- https://master.php.net/note/reject/113221 Search -- https://master.php.net/manage/user-notes.php
