note 86826 added to function.rand

*** Moderator *** please replace or delete my comment from Oct 10 as there is an error in the function I posted. Below is the corrected version. Thanks!!! *** This is a function to generate numbers of any length which contain no identical characters side-by-side. i.e. 11aa22bb33 <?php function createRandom($number_of_digits=1,$type=3){ // type: 1 - numeric, 2 - letters, 3 - mixed. for($x=0;$x<$number_of_digits;$x++){ while(substr($num,strlen($num)-1,strlen($num)) == $r){ switch($type){ case "1": $r = rand(0,9); break; case "2": $r = chr(rand(0,25)+65); break; case "3": if(is_numeric(substr($num,strlen($num)-1,strlen($num)))){ $n = rand(0,999); if($n % 2){ $r = chr(rand(0,25)+65); } else { $r = strtolower(chr(rand(0,25)+65)); } } else { $r = rand(0,9); } break; } } $new_string .= $r; } return $new_string; } // Usage Examples Below - // $number = createRandom(10); // echo $number; // Output: 6Q1a8C1u9S // echo createRandom(10,1); // Output: 8754381046 // echo createRandom(10,2); // Output: dNAoQYOtud // echo createRandom(); // Output: 9 ?> ---- Server IP: 69.147.83.197 Probable Submitter: 72.216.6.122 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/86826 Del: integrated -- https://master.php.net/note/delete/86826/integrated Del: useless -- https://master.php.net/note/delete/86826/useless Del: bad code -- https://master.php.net/note/delete/86826/bad+code Del: spam -- https://master.php.net/note/delete/86826/spam Del: non-english -- https://master.php.net/note/delete/86826/non-english Del: in docs -- https://master.php.net/note/delete/86826/in+docs Del: other reasons-- https://master.php.net/note/delete/86826 Reject -- https://master.php.net/note/reject/86826 Search -- https://master.php.net/manage/user-notes.php
