How Can I control Raspberry 3 GPIO Port from remote server in a php file

Hi ;

I am working on a project. I wanna control GPIO ports from a php file in a remote server. But the php file can't working properly on raspberry pi 3.

I try call a pyton script in php file.

How can access the gpio ports from remote php file to control local devices;

Example; I am using a server (that server contains the controller php file) , the remote raspberry that connected monitor will connect the server, i wanna open or close the monitor)

I have made a system where a web page controls three (or four) relays. Those relays were (ehh ARE!) connected to little FETs connected to the GPIOS.

In my case I just wrote a little php script that did something like
if (isset ($_POST["out1"])
system ("gpio write 1 " . $_POST["out1"]);
Note that like this, this would be a glaring security hole, you need to make sure that the user can only specify "0" or "1" in the place where I have $_POST["out1"] .

If you run the Python on the Raspberry Pi 3, check this Setting Up Your Raspberry Pi for Python GPIO Projects . If the server is on the Raspberry Pi 3, then https://www.raspberrypi.org/documentation/remote-access/web-server/apache.md will help you set that up. this way you can use PHP and connect to the web server on the Pi.
But this will alow direct get/post to the Raspberry Pi https://nayarweb.com/blog/2014/control-raspberry-pis-gpio-with-rest-qt-webiopi/
