note 76885 added to function.mt-rand

I tested the two functions that return multiple unique random numbers, which I've found between the comments for mt_rand() and rand(): - mrand($l,$h,$t,$len=false) - random_number_array($count, $from, $to) Here are the test results: http://www.bf.uni-lj.si/bi/mikroskopija/rand.php Clearly the better one is mrand(); <?php # Multiple Unique Random Numbers # # array mrand ( int min, int max, int count [, int strlen ] ) function mrand($l,$h,$t,$len=false){ if($l>$h){$a=$l;$b=$h;$h=$a;$l=$b;} if( (($h-$l)+1)<$t || $t<=0 )return false; $n = array(); if($len>0){ if(strlen($h)<$len && strlen($l)<$len)return false; if(strlen($h-1)<$len && strlen($l-1)<$len && $t>1)return false; do{ $x = rand($l,$h); if(!in_array($x,$n) && strlen($x) == $len)$n[] = $x; } while(count($n)<$t); }else{ do{ $x = mt_rand($l,$h); if(!in_array($x,$n))$n[] = $x; }while(count($n)<$t); } return $n; } ?> ---- Server IP: 213.250.2.28 Probable Submitter: 153.5.62.197 ---- Manual Page -- http://www.php.net/manual/en/function.mt-rand.php Edit -- https://master.php.net/note/edit/76885 Del: integrated -- https://master.php.net/note/delete/76885/integrated Del: useless -- https://master.php.net/note/delete/76885/useless Del: bad code -- https://master.php.net/note/delete/76885/bad+code Del: spam -- https://master.php.net/note/delete/76885/spam Del: non-english -- https://master.php.net/note/delete/76885/non-english Del: in docs -- https://master.php.net/note/delete/76885/in+docs Del: other reasons-- https://master.php.net/note/delete/76885 Reject -- https://master.php.net/note/reject/76885 Search -- https://master.php.net/manage/user-notes.php
