Code to create a UUID

PHP Code:

/**
 * guidV4 ()
 * -----------------------------------------------------------------------
 *
 * A universally unique identifier (UUID) it is a 128-bit number
 * used to identify information in computer systems.
 *
 * xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx
 *
 */
if ( ! function_exists('guidV4'))
{
    /**
     * guidV4 ()
     * -------------------------------------------------------------------
     *
     * @return string
     */
    function guidV4()
    {
        // Microsoft guid {xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx}
        if (function_exists('com_create_guid') === true)
        {
            return trim(com_create_guid(), '{}');
        }

        $data = openssl_random_pseudo_bytes(16);

        // set version to 0100
        $data[6] = chr(ord($data[6]) & 0x0f | 0x40);

        // set bits 6-7 to 10
        $data[8] = chr(ord($data[8]) & 0x3f | 0x80);

        return vsprintf('%s%s-%s-%s-%s-%s%s%s', str_split(bin2hex($data), 4));
    }
} 


For Bar-codes you can use this library.
