note 88755 added to function.rand

Dear "shortschoolbus at live dot com"! Your code has not worked me, so i have rewrite: function createRandom($number_of_digits=1,$type=3){ // type: 1 - numeric, 2 - letters, 3 - mixed. for($x=0;$x<$number_of_digits;$x++){ switch($type){ case "1": $r = rand(0,9); break; case "2": $r = chr(rand(0,25)+65); break; case "3": $n = rand(0,999); if($n % 2){ $n = rand(0,999); if($n % 2){ $r = chr(rand(0,25)+65); } else { $r = strtolower(chr(rand(0,25)+65)); } } else { $r = rand(0,9); } } $new_string .= $r; } return $new_string; } I have just tried to use your function, but it has not work well. First time it hase make just number and all numbers were the same, like print(createRandom(10)); // 5555555555 I do not know why have you write: while(substr($num,strlen($num)-1,strlen($num)) == $r){ } Because this, it hase make just the same characters in the string. When i have removed that, it has made just numbers, so the next bug was in the switch case"3": if(is_numeric(substr($num,strlen($num)-1,strlen($num)))){ I have rewrite it and then it has worked well. $n = rand(0,999); if($n % 2){ ... ---- Server IP: 92.43.200.200 Probable Submitter: 77.234.65.108 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/88755 Del: integrated -- https://master.php.net/note/delete/88755/integrated Del: useless -- https://master.php.net/note/delete/88755/useless Del: bad code -- https://master.php.net/note/delete/88755/bad+code Del: spam -- https://master.php.net/note/delete/88755/spam Del: non-english -- https://master.php.net/note/delete/88755/non-english Del: in docs -- https://master.php.net/note/delete/88755/in+docs Del: other reasons-- https://master.php.net/note/delete/88755 Reject -- https://master.php.net/note/reject/88755 Search -- https://master.php.net/manage/user-notes.php
