std::string uid = ""; uuid_t uu; int i; uuid_generate(uu); for (i = 0; i < 16; i ++) { char aa[10]=""; sprintf(aa, "%02X",uu[i]); uid+=aa; } return uid;
$length){ $string = substr($string, 0,$length); } } function create_guid_section($characters){ $return = ""; for ($i = 0;$i < $characters;$i++){ $return.=dechex(mt_rand(0, 15)); } return $return; } ?>
