PHP Warning: exec() has been disabled Alternative?

[techker]

Hey guy's i doing a Rasperry Pi garage door app and got this code in a tutorial:

 

$q=$_GET["q"];

 

if(isset($_GET['q']) && $_GET['q'] == 1) {

error_reporting(E_ALL);

exec('gpio write 7 0');

usleep(1000000);

exec('gpio write 7 1');

echo" garage is Open";

} 

 

i modified it to return a response.

 

but i get an error file from server

 

PHP Warning:  exec() has been disabled for security reasons in /home/techker/public_html/Garage/getcd.php on line 15

 

is there an alternative or way around this ?

And what exactly prevents you from enabling the function? Adjust the disable_functions parameter in your php.ini.

i don't think i have access...i will check the cpanel to see

Then you may be out of luck.

 

The PHP manual gives you a collection of functions which can be used as an alternative to system(), but it's hard to imagine that they've disabled system() while keeping equivalent functions enabled. This wouldn't make any sense.

i sent out a request .. in the cpanel i only have basic php ini values that i can mod....

...Shouldn't this code be running on the Pi? Your Pi? That I assume you have full control over?

Apache is a bit of a hog. Consider nginx instead.
