Question

I have this

$resizeObj -> saveImage('images/'.$pic, 90);

and I want to append random characters at the end of file name in order to prevent duplicate names using somethign like this:

    function genRandomString() {
    $length = 10;
    $characters = ’0123456789abcdefghijklmnopqrstuvwxyz’;
    $string = ”;    

    for ($p = 0; $p < $length; $p++) {
        $string .= $characters[mt_rand(0, strlen($characters))];
    }

    return $string;
}

Whta is the best way to incorporate this into $resizeObj

Answer 1

You should not save random string. Just append a unique string (eg. uniqid()) when you present the image.
