Generate limit UUID code

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.

I try it Thanks
