Random Number

I'm using the session id as a random number. I want to limit the length of the string to 8 characters. How would I do this using the following statement? I looked everywhere on the web.

<input type="hidden" name="Quote_number" id="Quote_number" value="<?php echo session_id(); ?>" />

<?php echo substr(session_id(), 0, 8); ?>

But once you only take the first eight characters, it may no longer be truly unique.

use the substr() function:

php:
<input type="hidden" name="Quote_number" id="Quote_number" value="<?php echo substr(session_id(), 08); ?>" />
