Generating a unique random string of a certain length and restrictions in PHP?
<p>I have the need to generate a random alphanumeric string of 8 characters. So it should look sort of like <code>b53m1isM</code> for example. Both upper and lower case, letters and numbers.</p>

<p>I already have a loop that runs eight times and what I want it to do is to concatenate a string with a new random character every iteration. </p>

<p>Here's the loop:</p>

<pre><code>$i = 0;
    while($i &lt; 8)
    {
        $randPass = $randPass + //random char
        $i = $i + 1;
    }
</code></pre>

<p>Any help?</p>
