PHP：如何循环访问目录中的每个XML文件？ [英] PHP: How do I loop through every XML file in a directory?
问题描述
基本上，系统将这样工作：
-
其他公司将其采购订单上传到我们的FTP服务器。这些订单是简单的XML文件（包含客户数据，地址信息，订购产品和数量等）...
-
我已经建立了一个简单的用户界面HTML5，jQuery和CSS都是由PHP提供支持。
-
PHP读取订单的内容（使用SimpleXML的内置功能）并将其显示在该网页。
所以，它是一个网络应用程序，应该总是在办公室的浏览器中运行。 PHP应用程序将显示所有订单的内容。每十五分钟左右，应用程序将检查新订单。
如何循环访问目录中的所有XML文件？
现在，我的应用程序能够读取单个XML文件的内容，并以一种漂亮的方式在页面上显示。
我当前的代码如下所示：
//选择我知道的随机订单存在于订单中目录：
$ xml_file = file_get_contents（Order / 6366246.xml，FILE_TEXT）;
$ xml = new SimpleXMLElement（$ xml_file）;
// start echo基本订单信息，如订单号：
echo $ xml-> OrderHead-> ShopPO;
//有关订单的更多信息和客户进入这里...
echo< ul>;
//循环遍历每个订单行，并回显所有数量和产品：
foreach（$ xml-> OrderLines-> OrderLine as $ orderline）{
< ; li>$ orderline-> Quantity。st。< / li> \\\
。
< li>$ orderline-> SKU。< / li> \\\
;
}
echo< / ul>;
//有关送货选项，地址信息等的更多信息等等...
所以，那是我的代码。很简单它只需要做一件事 - 打印屏幕上所有订单文件的内容 - 所以我和我的同事可以看到订单，确认并交付。
就是这样。
但现在，您可以看到 - 我一次选择一个订单，位于订单目录中。但是如何循环遍历整个订单目录，并阅读并显示每个订单的内容（如上所述）？
我被卡住了。我真的不知道如何将所有（xml）文件放在一个目录中，然后用文件进行某些操作（比如读取它们并回显数据，就像我想要的那样）。
- >我真的很感激一些帮助。我对PHP /服务器端编程不是很有经验，所以如果你能帮助我在这里，我将非常感激。
提前感谢！

欢迎来到SO。
尝试 glob 功能：
$ files = glob（Order / * xml）;
if（is_array（$ files））{
foreach（$ files as $ filename）{
$ xml_file = file_get_contents（$ filename，FILE_TEXT）;
//并继续执行代码
}
}
I'm building a simple application. It's a user interface to an online order system.
Basically, the system is going to work like this:
Other companies upload their purchase orders to our FTP server. These orders are simple XML files (containing things like customer data, address information, ordered products and the quantities…)
I've built a simple user interface in HTML5, jQuery and CSS — all powered by PHP.
PHP reads the content of an order (using the built-in features of SimpleXML) and displays it on the web page.
So, it's a web app, supposed to always be running in a browser at the office. The PHP app will display the content of all orders. Every fifteen minutes or so, the app will check for new orders.
How do I loop through all XML files in a directory?
Right now, my app is able to read the content of a single XML file, and display it in a nice way on the page.
My current code looks like this:
// pick a random order that I know exists in the Order directory:
$xml_file = file_get_contents("Order/6366246.xml",FILE_TEXT);
$xml = new SimpleXMLElement($xml_file);
// start echo basic order information, like order number:
echo $xml->OrderHead->ShopPO;
// more information about the order and the customer goes here…
echo "<ul>";
// loop through each order line, and echo all quantities and products:
foreach ($xml->OrderLines->OrderLine as $orderline) {
"<li>".$orderline->Quantity." st.</li>\n".
"<li>".$orderline->SKU."</li>\n";
}
echo "</ul>";
// more information about delivery options, address information etc. goes here…
So, that's my code. Pretty simple. It only needs to do one thing — print out the content of all order files on the screen — so me and my colleagues can see the order, confirm it and deliver it.
That's it.
But right now — as you can see — I'm selecting one single order at a time, located in the Order directory. But how do I loop through the entire Order directory, and read aand display the content of each order (like above)?
I'm stuck. I don't really know how you get all (xml) files in a directory and then do something with the files (like reading them and echo out the data, like I want to).
--> I'd really appreciate some help. I'm not very experienced with PHP/server-side programming, so if you could help me out here I'd be very grateful.
Thanks a lot in advance!

welcome to SO.
Try the glob function:
$files = glob("Order/*xml");
if (is_array($files)) {
foreach($files as $filename) {
$xml_file = file_get_contents($filename, FILE_TEXT);
// and proceed with your code
}
}
