    You can use rand function of php to generate random number and you can take part of the session_id to generate random string , if you combine both of them it will give you required result

            Here's another way to do it...

            $randomString = md5(rand());

        <?php

        function RandomTxt() {
        $chars = "thequickbrownfoxjumpsoverthelazydog";
        srand((double)microtime()*1000000);
        $i = 0;
        $pass = '' ;
        while ($i <= 10) {
        $num = rand() % 33;
        $tmp = substr($chars, $num, 1);
        $pass = $pass . $tmp;
        $i++;
        }

    You can geenrate very good random string by session and md5 combination

    echo md5(substr(session_id(),0,10));
    You can use both the function together and get good string
