I am new to RPi so sorry if this is a green question I’m trying to control the raspberry pi from a webpage so I am testing out with a single LED.. I installed Apache, php, and WiringPi successfully and got the “It works” page. But when I configure the code to turn on the GPIO pin for the LED it simply shows the code instead of turning on the LED. Any help is appreciated!

php code (in /var/www/html)

<?php

    system(“gpio -g mode 4 out”);
    system(“gpio -g write 4 1”);

Do you really have those curly quotes in there? `“`. Shouldn't those be regular quotes? `"`. – Funk Forty Niner Jun 20 '20 at 21:03
They are regular quotes on my Pi, just shows “ as I typed this question from my phone.. GPIO labelling is BCM here right? – patriciajlim Jun 20 '20 at 21:14
Ah ok. Well, this is out of my league stuff. I am not the guy for this. – Funk Forty Niner Jun 20 '20 at 21:26
can you browse to this page in a regular browser? if so what do you see? – Clint Jun 20 '20 at 22:35
Yup. On my phone comes out exactly the same - just the code, doesn’t do anything to the LED – patriciajlim Jun 21 '20 at 00:29
