http://php.net/manual/en/function.rand.php

 

The manual has awesome information, like this post:

 

<?php
// Generate a random character string
function rand_str($length = 32, $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890')
{
    // Length of character list
    $chars_length = (strlen($chars) - 1);

    // Start our string
    $string = $chars{rand(0, $chars_length)};
   
    // Generate random string
    for ($i = 1; $i < $length; $i = strlen($string))
    {
        // Grab a random character from our list
        $r = $chars{rand(0, $chars_length)};
       
        // Make sure the same two characters don't appear next to each other
        if ($r != $string{$i - 1}) $string .=  $r;
    }
   
    // Return the string
    return $string;
}
?>

Last post is one way

 

or

 

$random_str = substr(uniqid('Z'),-15,15);

[dbradbury]

[jl5501]

I think you will find it only uses lower case letters
