如何设置 xml 属性并将更改保存到文件？

Question

我需要使用 PHP 更改 xml 属性（即名称、Phone1、Phone2）。更改的属性值需要保存到从中获取代码的文件中。 谁能让我走上正轨？

Answer 1

您可以使用setAttribute

public DOMAttr DOMElement::setAttribute ( string $name , string $value )

Answer 2

您可以简单地使用 PHP: XMLWriter 来实现这一点： http://php.net/manual/de/function.xmlwriter-write-element.php

也用于读取 XML 文件： http://php.net/manual/en/simplexml.examples-basic.php

它是您的网络服务器上的远程 XML 还是本地的？ - 问题是你不能即时编辑远程文件，我想。 最好的方法是获取旧的，在解析 XML 时更改值并再次保存。
