PHP with Raspberry Pi

I am controlling my garage door using a Raspberry Pi. I want to add a magnetic switch to tell if the door is open or closed.

Any idea where to start?

Here is what I have so far:

<!DOCTYPE html>

<html lang="en">
<head>
<meta name="generator" content=
"HTML Tidy for Linux (vers 6 November 2007), see www.w3.org">
<meta charset="utf-8">

<title>Garage Remote</title>


<script type="text/javascript">

window.onload = function(){

buttonOff = document.getElementById('submitPressed');
buttonOff.onClick = relayOff;
}

function relayOff(){

hidden = document.getElementById("total");
hidden.value = "pressed";

form = document.getElementById("relay");
form.method = "GET";
form.action = "remote.php";
form.submit();
}
</script>


<script type="text/javascript">
function setColor(btn,color){

var property=document.getElementById(btn);
if (window.getComputedStyle(property).backgroundColor == 'rgb(244, 113, 33)') {
property.style.backgroundColor=color;
}
else {
property.style.backgroundColor = "#2159F4";
}
}
</script>
</head>

<body>
<form id="relay" action="remote.php" method="get">
<input type="button" id="submitPressed" style=
"border:1px solid #000; font-size:80px;" value="Open/Close"
onclick="relayOff();setColor('submitPressed','#fff200');">
<input type="hidden" name="total" id="total" value="">
</form>
<?php

exec("gpio -g mode 17 out");
$state = $_GET["total"];

if ($state == "off"){
exec("gpio -g write 17 1");
sleep(1);
exec("gpio -g write 17 0");
}

?>

</body>
</html>

Where is the web server that is running PHP?

It is running on the Pi.

Interesting, didn't realize that Raspberry Pi could run all that. I have never used PHP to control hardware. I suggest you click on "Request Attention" above to get others to look at your question.
