I want to write a donation system with the simplest form of PHP programming language.
The first step is to generate a bitcoin address.
I will generate the QR code for this bitcoin address and put it on the site.
The screen I imagine is as follows:

You could use a coinbase wallet users send donations to and use the Coinbase API to get the transactions.

Since you are not looking to generate a unique address for each user then you should simply put an address that fits you and then gather transactions that gets sent to it with the balance , I suggest using the blocktrail API here : https://www.blocktrail.com/api/docs and you could use the sample given and explained here : http://bitcoin.stackexchange.com/questions/34300/how-to-get-the-list-of-transactions-that-has-gone-into-an-address-with-the-amoun

There's really no need for PHP, you could do it client-side with javascript and websocket. In fact I just did a blog post for blockchain.info on how to do this. https://blog.blockchain.com/2017/01/04/intro-to-bitcoin-development/

However if you really want PHP it's easy enough, but new donations won't show up LIVE unless you use something like websocket or AJAX.

Code:

<?php
$address = "YOUR_BTC_ADDRESS";

$qrurl = "http://chart.googleapis.com/chart?chs=125x125&cht=qr&chl=".$address;
$qrcode = "<img src='".$qrurl."'>";
//this is just an image created using google charts API

//get JSON data on address using blockchain.info free public API
$url = "https://blockchain.info/address/".$address."?format=json";
$json = json_decode(file_get_contents($url), true);

?>
<html>
<body>
Bitcoin Donations Accepted
<br>
<?php echo $qrcode; ?>
<br>
<table>
<tr>
   <td>Received From</td>
   <td>Amount</td>
</tr>
<?php
//loop through the last 4 received donations
for($i=0;$i<5;$i++){
   $outputs = count($json["txs"][$i]["out"]);
   //loop through each output of the tx
   for($ii=0;$ii<$outputs;$ii++){
      //check if output addy matches our donation addy
      $outaddy = $json["txs"][$i]["out"][$ii]["addr"];
      $value = $json["txs"][$i]["out"][$ii]["value"];
      $value = $value / 100000000;
      if($outaddy == $address){
          echo "<tr><td>".$json['txs'][$i]['inputs'][0]['prev_out']['addr']."</td><td>".$value."BTC</td></tr>";
      }
   }
}
?>
</table>
</body>
</html>
