note 79422 added to function.microtime

@zenofeller at zenofeller dot com: I was trying to point out that randomString() significantly reduces the "randomness-per-byte" compared to what mt_rand() and friends gives you to begin with - eg. making it more "predictable". If you're looking to generate hard-to-predict printable keys and cares about the length of the key (you perhaps need to stick in in a CHAR(32) field of some db-table), you'd be better off with either my rstr() or md5(uniqid(rand(), true)); which both will provide you with a much larger keyspace (and thus a smaller chance of a collision) in the same amount of bytes as randomString(). I should have said "more predictable" instead of just "predictable" in my previous post; you're indeed correct when you say that randomString() _will_ give you random data. It most definitely does, it just doesn't do so very effectively :) ---- Server IP: 128.39.198.38 Probable Submitter: 193.91.135.250 ---- Manual Page -- http://www.php.net/manual/en/function.microtime.php Edit -- https://master.php.net/note/edit/79422 Del: integrated -- https://master.php.net/note/delete/79422/integrated Del: useless -- https://master.php.net/note/delete/79422/useless Del: bad code -- https://master.php.net/note/delete/79422/bad+code Del: spam -- https://master.php.net/note/delete/79422/spam Del: non-english -- https://master.php.net/note/delete/79422/non-english Del: in docs -- https://master.php.net/note/delete/79422/in+docs Del: other reasons-- https://master.php.net/note/delete/79422 Reject -- https://master.php.net/note/reject/79422 Search -- https://master.php.net/manage/user-notes.php
