LED Control:
<form method="get" action="gpio.php">
<input type="submit" value="ON" name="on">
<input type="submit" value="OFF" name="off">

<?php
$setmode17 = shell_exec("/usr/local/bin/gpio -g mode 17 out");
$setmode22 = shell_exec("/usr/local/bin/gpio -g mode 22 out");
$setmode27 = shell_exec("/usr/local/bin/gpio -g mode 27 out");
$setmode04 = shell_exec("/usr/local/bin/gpio -g mode 04 out");
if(isset($_GET['on'])){
$gpio_on = shell_exec("/usr/local/bin/gpio -g write 17 1");
$gpio_on = shell_exec("/usr/local/bin/gpio -g write 22 1");
$gpio_on = shell_exec("/usr/local/bin/gpio -g write 27 1");
$gpio_on = shell_exec("/usr/local/bin/gpio -g write 04 1");
echo "LED is on";
}
else if(isset($_GET['off'])){
$gpio_on = shell_exec("/usr/local/bin/gpio -g write 17 0");
$gpio_on = shell_exec("/usr/local/bin/gpio -g write 22 0");
$gpio_on = shell_exec("/usr/local/bin/gpio -g write 27 0");
$gpio_on = shell_exec("/usr/local/bin/gpio -g write 04 0");
echo "LED is off";
}
?>

this is a code of my led control page, only 17 and 22 are working, and is there a differencce in wiring numbers / pin numbers of actual raspi3 in wiringpi? or am i doing something wrong?
