抱歉，我没有足够的声誉发表评论，但这里是 Edward Ocampo-Gooding 的回答中的死链接的内容：
PHP 示例 w/ SimpleXML (PHP 5+)
下面的脚本向您展示了如何将 XML 数据从 Shopify 获取到您的脚本中、归档文件并发送正确的标题...
鉴于 webhook 管理员中的新订单订阅设置为：http ://example.com/some-script.php?key=123456789
http://example.com/上 some-script.php 的内容：
<?
// Protect URL from rogue attacks/exploits/spiders
// Grab from GET variable as given in Shopify admin URL
// for the webhook
//
// NOTE: This is not necessary, just a simple verification
//
// A digital signature is also passed along from Shopify,
// as is the shop's domain name, so you can use one or both of those
// to ensure a random person isn't jacking with your script (or some
// spider just randomly hitting it to see what's there).
//
// If $key doesn't matched what should be passed in from the
// webhook url, the script simply exits
$key = $_GET['key'];
if ($key != '123456789') {
header('HTTP/1.0 403 Forbidden');
exit();
}
// Variables used for processing/saving
$xmlString = ; // Used to get data from Shopify into script
$name = ; // Saves the billing address name to be used for later ...
$email = ; // Save the email address of the user to be used for later ...
$productTitles = array(); // Saves all titles of products purchased to be used for later ...
// Get XML data and read it into a string for use with SimpleXML
// Thanks to David Oxley (http://www.numeriq.co.uk) for help with this
$xmlData = fopen('php://input' , 'rb');
while (!feof($xmlData)) { $xmlString .= fread($xmlData, 4096); }
fclose($xmlData);
// Save order XML in file in orders directory
// This creates a file, write the xml for archival purposes, and closes the file ...
// If the file already exists, it appends the data ... this should create a separate
// file for every order but if two orders are processed the same second, they'll both
// be in the same file
file_put_contents('orders/order' . date('m-d-y') . '-' . time() . '.xml', $xmlString, FILE_APPEND);
// Use SimpleXML to get name, email, and product titles
// SimpleXML allows you to use the $xml object to easily
// retrieve the data ...
// Please note, if hyphens are used in the xml node, you must
// surround the call to that member with {'member-name'} as is
// shown below when getting the billing-address name & the
// line items
$xml = new SimpleXMLElement($xmlString);
$name = trim($xml->{'billing-address'}->name);
$email = trim($xml->email);
// Create productTitles array with titles from products
foreach ($xml->{'line-items'}->{'line-item'} as $lineItem) {
array_push($productTitles, trim($lineItem->title));
}
// You would then go on using $name, $email, $productTitles in your script
// to do whatever the heck you please ...
// Once you are done doing what you need to do, let Shopify know you have
// the data and all is well!
header('HTTP/1.0 200 OK');
exit();
// If you want to tell Shopify to try sending the data again, i.e. something
// failed with your processing and you want to try again later
header('HTTP/1.0 400 Bad request');
exit();
