Try this, it worked for me.

$numLenth = 35;

function make_seed_Token() {
  list($usec, $sec) = explode(' ', microtime());
  return (float) $sec + ((float) $usec * 100000);
}

srand(make_seed_Token());

$numSeed = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
$getNumber = "";
for($i = 0; $i < $numLenth; $i ++) {
 $getNumber .= $numSeed[rand(0, strlen($numSeed))];

}

echo $getNumber;
