从Codeigniter执行Python文件

Question

I have some trouble to execute a Python file from a Codeigniter controller's function.

~/application/controllers/Lights.php :

header("Access-Control-Allow-Origin: *");
class Lights extends CI_Controller {
    public function __construct() {
        parent::__construct ();
        $this->load->helper ( array ('url', 'form') );
    }
    public function turnOn() {
        system('sudo python test.py > /dev/null 2>/dev/null &');
    }
}

but when I try to execute a system call, like :

system("sudo gpio mode 15 out");

this works perfectly.

Answer 1

Provide the full path to python binary and script, i.e.:

system('/full/path/to/python /full/path/to/test.py > /dev/null 2>/dev/null &');

If the python binary is already on the PATH of your apache user (apache/www-user), you may ignore the full path.
