Here is what I use to generate them, place this into any of your helper files.
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));
}
}
You can also modify it to include a namespace if you want.
What did you Try? What did you Get? What did you Expect?
