android - Synchronizing Database with server by use of a checksum -

-

in application store data server on first time login db. on each of next login (or after periodic interval of time) need mechanism check updation , if there exists 1 download updated data , update local db.

there proposition use sort of checksum calculated @ local end , match checksum coming server. how implement execution of checksum update data. there other recommendations achieve same task timestamp?

can associate timestamp tables instead of being column in db?

solution:

this have implemented this: there no need of checksum though. each , every table in database has column indicate last update timestamp particular row. , last update timestamp tables stored in different table altogether. timestamp sent server fetch update in data.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875
