创建新的XML文件并向其写入数据?

I need to create a new XML file and write that to my server. So, I am looking for the best way to create a new XML file, write some base nodes to it, save it. Then open it again and write more data.

我需要创建一个新的XML文件并将其写入服务器。因此，我正在寻找创建一个新的XML文件、为它编写一些基本节点、保存它的最佳方法。然后再次打开它并编写更多的数据。

I have been using file_put_contents() to save the file. But, to create a new one and write some base nodes I am not sure of the best method.

我一直在使用file_put_contents()保存文件。但是，要创建一个新的节点并编写一些基节点，我不确定最好的方法是什么。

Ideas?

DOMDocument is a great choice. It's a module specifically designed for creating and manipulating XML documents. You can create a document from scratch, or open existing documents (or strings) and navigate and modify their structures.

DOMDocument是一个不错的选择。它是专门为创建和操作XML文档而设计的模块。您可以从头创建一个文档，或者打开现有文档(或字符串)，导航和修改它们的结构。

$xml = new DOMDocument();
$xml_album = $xml->createElement("Album");
$xml_track = $xml->createElement("Track");
$xml_album->appendChild( $xml_track );
$xml->appendChild( $xml_album );

$xml->save("/tmp/test.xml");

To re-open and write:

重新写:

$xml = new DOMDocument();
$xml->load('/tmp/test.xml');
$nodes = $xml->getElementsByTagName('Album') ;
if ($nodes->length > 0) {
   //insert some stuff using appendChild()
}

//re-save
$xml->save("/tmp/test.xml");

PHP has several libraries for XML Manipulation.

PHP有几个用于XML操作的库。

The Document Object Model (DOM) approach (which is a W3C standard and should be familiar if you've used it in other environments such as a Web Browser or Java, etc). Allows you to create documents as follows

文档对象模型(DOM)方法(是W3C标准，如果您在其他环境(如Web浏览器或Java等)中使用过它，那么应该很熟悉它)。允许您创建如下文档

<?php
    $doc = new DOMDocument( );
    $ele = $doc->createElement( 'Root' );
    $ele->nodeValue = 'Hello XML World';
    $doc->appendChild( $ele );
    $doc->save('MyXmlFile.xml');
?>

Even if you haven't come across the DOM before, it's worth investing some time in it as the model is used in many languages/environments.

即使您以前没有遇到过DOM，也值得花一些时间在它上，因为模型在许多语言/环境中使用。

With FluidXML you can generate and store an XML document very easily.

使用FluidXML，您可以很容易地生成和存储XML文档。

$doc = fluidxml();

$doc->add('Album', true)
        ->add('Track', 'Track Title');

$doc->save('album.xml');

Loading a document from a file is equally simple.

从文件中加载文档同样简单。

$doc = fluidify('album.xml');

$doc->query('//Track')
        ->attr('id', 123);
