How to get string of fixed length without using rand() function

Question

How to get a fixed length string without using the rand() function?

I have this but I do not want to use the rand() function

function generateRandomString($length =6) {
    $characters = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $charactersLength = strlen($characters);
    $randomString = '';

    for ($j = 0; $j < $length; $j++) {
        $randomString .= $characters[mt_rand(0, $charactersLength - 1)];
    }

  return $randomString;
 }

*"How to get fixed length srting without using rand() function"* `function x(){return "fixed length";}`. (No seriously, why don't you want to use `rand()`?) — Rizier123, Apr 27 '16 at 10:08

<?php
$start=0;$length=6;
$str='0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';
$Val=substr(str_shuffle($str),$start,$length);
echo $Val;

function mt_rand_str ($l, $c = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890') {

     for ($s = '', $cl = strlen($c)-1, $i = 0; $i < $l; $s .= $c[mt_rand(0, $cl)], ++$i);
        return $s;
}

Here you can call this function for 8 character

mt_rand_str(8)
