Use of System.err.println() in Java -

-

on standard console things printed in white whether have written in system.out or system.err. in ide(for me eclipse) can see different color output on console both. i.e. black system.out , red system.err.

is system.err provided use in ides? cause on cmd can not distinguish system.out , system.err. both printed in same color.

these 2 different output streams available in of os's. don't have them color coded due settings of terminal/command line environment. on other hand ide provides different visualization different streams.

if wanted color them, consider using ansi escape sequences.

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
