XML;

作为第一次进行XML解析体验，我希望有人能告诉我如何进行并将其转换为php数组或类似的东西，以便我可以将我想要的数据插入到mysql表中。

最简单的方法是什么？

Answer 1

您可以使用PHP XML解析器，例如SimpleXML

Answer 2

您可以将以下代码段与xml_parse_into_struct一起使用，将您的XML分成两个PHP数组，一个包含数据，另一个包含指向values数组中显示的标记的位置：

$parser = xml_parser_create();

$values = array();
$index = array();

xml_parse_into_struct  ($parser, $xml, &$values, &$index);

var_dump($values);
var_dump($index)

$ xml包含XML数据。查看我链接到的手册页中的示例以获取更多信息。

Answer 3

您可以使用builtin XML parser，手册应该为您提供所需的一切。但是从经验来讲，我真的建议学习Xpath，因为它很多更快，更容易使用，然后你可以通过PHP得到任何其他东西。您可以从introduction@w3schools开始，查看nice examples in the specs并最终使用PHP functions。

用于选择交易ID的示例查询将是

$document = new DOMDocument();
$document->load('YourFile.xml');
$xpath = new DOMXPath($document);

# Query id
$ids = $xpath->query('/transactions/transaction/id/text()');
# $ids is a DOMNodeList object
assert($ids->length === 1);
$id = $ids->item(0);

# Query date
$dates = $xpath->query('/transactions/transaction/transaction_date/text()');
# $dates is a DOMNodeList object
assert($dates->length === 1);
$id = $dates->item(0);

Answer 4

最好是使用PHP XML Parser。 IMO，最好是使用PHP DOM，因为在每种语言（或左右）中，您都可以使用相同的方法找到这个库。

Answer 5

解析XML：
如果您的服务器只接收XML（不在$ _POST ['xmlfeed']中）：

$xml = file_get_contents("php://input");  
$data = simplexml_load_string ($xml);

不要将SimpleXML对象转换为数组。无论如何，它的工作方式非常类似于数组。您可以使用foreach，并且可以轻松访问其元素 http://us2.php.net/manual/en/simplexml.examples-basic.php

P.S。对于大型XML文档，请使用XMLReader（）而不是SimpleXML。
