将字符串类型从curl转换为数组

Question

我正在使用这个卷曲代码：

$key='the_key'; 
$url='http://api-product.skimlinks.com/categories?key='.$key.'&format=xml';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result=curl_exec($ch);
var_dump($result);

这给了我以下字符串

string(575317) "<?xml version='1.0' encoding='UTF-8'?>
<skimlinksProductAPI><status>200

只是一堆类别，它只是证明字符串是完全不可读的，有没有办法实际将这个XML响应作为一个带有curl的数组？它是一个直接数组还是需要以手动方式将字符串转换为数组，如果是，那么最好的程序是什么。

Answer 1

CURL无法对XML做任何事情。一些API将为您提供seralised数组和JSON响应。检查两者是否更容易处理。否则，您将需要使用PHP DOM来读取XML并将其转换为数组：

What is the best php DOM 2 Array function?

Answer 2

您应该使用SimpleXML扩展名和simplexml_load_string函数从字符串中创建XML对象。之后，您可以像使用任何其他对象一样简单地使用它并将其转换为数组（如果需要）。
