}?>string com_create_guid ( void )
The phunction PHP framework (http://sourceforge.net/projects/phunction/) uses the following function to generate valid version 4 UUIDs:
<?phpfunction GUID()
{
if (function_exists('com_create_guid') === true)
{
return trim(com_create_guid(), '{}');
}
return sprintf('%04X%04X-%04X-%04X-%04X-%04X%04X%04X', mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(16384, 20479), mt_rand(32768, 49151), mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(0, 65535));
}?>
The output generated by the sprintf() and mt_rand() calls is identical to com_create_guid() results.

Function parse_ini_file doesn't parse a remote ini file if allow_url_include is off.
