Simple PHP-Web-Gpio example switching leds

  • Thanks for the pointers here @Rinus-van-Weert! I've managed to get PHP up and running without any fuss at all. Only last thing I'd add is whilst you're in modifying uhttpd you might want set up a secondary site.

    So in /etc/config/uhttpd I've added the following below the main config definition

    config uhttpd 'myapp'
            list listen_http ''
            list listen_http '[::]:4000'
            list interpreter '.php=/usr/bin/php-cgi'
            option home '/www/myapp'
            option cgi_prefix '/cgi-bin'
            option index_page 'index.php'
            option error_page '/oopsie.html'

    The benifit (for me) being that, if you wanted to, you can access this site from the wider world without exposing the console.

    Happy Hacking all šŸ˜›

  • @Bo-Barry got it loaded, now don't know to 'run it'. First time PHP.

  • @Rinus-van-Weert thanks for the example.
    find an small error on this line: "to the 'main' section of the /etc/config/uhhtpd file" => uhhtpd = uhttpd

    @Bo Barry you can run the program in your brouwser, http:\ipadres.for.onion\php\SwithcLeds.php
    (if you put the script in www/php as SwitchLeds.php)

    I have also a relay expansion and make 2 functions for this:

    function initRelay( ){ // init Relay expansion
        $command = 'relay-exp -i';
    	exec( $command ); //init 
    function writeRelay( $pen, $value){ 
    	if ( is_numeric( $value) )	// check if value is a number, could also be empty, if so write value tot output pin
    	{	$command = 'relay-exp ' .$pen .($value == 1 ?  ' 1' : ' 0');
    		$res = exec( $command );
    		echo $res;
    	return $value;

    but there is no way to get the status of the relays. you only now the status when init.

  • @Lazar-Demin Hi Lazar, After opkg update, php5-cgi installed and I was able to run PHP srcipts, like SwitchLeds and others. Thanks for the help. I had recently done the opkg update, so how often does it need to be run?

  • @Yale-E.-Goldman Package indexes are usually updated daily, so it's recommended that you do an opkg update before each opkg install.

  • @Boken-Lin @Rinus-van-Weert How can I install the "SwitchLeds.php" file directly to the onion omega? Thanks for the awesome example, I have been looking at making a project like this, but I had no idea whatsoever on what to do.

  • Hi, I have made a class that use this functions to control the Onion

    I found an other interesting topic here that use an other approach

  • @Kyle I use pscp from putty with flag -scp

    >PSCP.exe -scp -pw {onionpasw} source\* root@{onion.IP}:/www/php

    to copy source to php directory

  • @Kyle from your Omega, you can also do a wget to get the file

    wget --no-check-certificate https://community.onion.io/uploads/files/1446719911755-switchleds.php

  • @Anco-van-der-Kolk
