correct RandomPassword function :
function RandomPassword( $passwordLength ) {
$password = "";
for ($index = 1; $index <= $passwordLength; $index++) {
// Pick random number between 1 and 61
$randomNumber = rand(1, 61);
// Select random character based on mapping.
if ($randomNumber < 11)
$password .= Chr($randomNumber + 48 - 1); // [ 1,10] => [0,9]
else if ($randomNumber < 36)
$password .= Chr($randomNumber + 65 - 10); // [11,36] => [A,Z]
else
$password .= Chr($randomNumber + 97 - 36); // [37,62] => [a,z]
}
return $password;
}
