i not able run function using exec command can 1 out problem?.

codeigniter has page in it´s manual this:

http://ellislab.com/codeigniter/user-guide/general/cli.html

note that, in command, put path file, didn´t add "php"

$command = "php d:\xampp\php\php d:\xampp\htdocs\client\newslatter\index.php admin preget";

maybe solve problem.

is php.exe in "path" enviroment variable of windows?

the process should pretty easy: run > "cmd" in windows , navigate codeigniter project.

$ cd /path/to/project; $ php index.php yourcontroller controllermethod
