 * used to identify information in computer systems.

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));
    }
