Answer 1

There are so many ways you can create a salt string, but i think you don't need to think a lot about your salt strength.

I hash passwords like this

$hash = sha1(strlen($password) . md5($password) . $salt);

I think its the best performance between speed, and "security".

function salt($lenght = 9) {
    $numbers = '0123456789';
    $chars = 'qwertzuiopasdfghjklyxcvbnm';

    $password = '';
    $alt = time() % 2;
    for ($i = 0; $i < $length; $i++) {
        if ($alt == 1) 
        {
            $password .= $chars[(rand() % strlen($chars))];
            $alt = 0;
        } else 
        {
            $password .= $numbers[(rand() % strlen($numbers))];
            $alt = 1;
        }
    }
    return $password;
}
