How to access POST data in PHP?
提问by phihag
I need to write a PHP page which would accept an XML document sent over a POST request like this:
我需要编写一个 PHP 页面，该页面将接受通过 POST 请求发送的 XML 文档，如下所示：
POST /mypage.php HTTP/1.1
Host: myhost.com
Content-Type: application/xml
Content-Length: ...
<?xml version="1.0" encoding="utf-8"?>
<data>
...
</data>
This is not data from some HTML form, just a plain XML document.
这不是来自某些 HTML 表单的数据，只是一个普通的 XML 文档。

Read from php://input. For example, you could use:
从php://input. 例如，您可以使用：
$rawdata = file_get_contents('php://input');
or
或者
$rootNode = simplexml_load_file('php://input');
The alternative, using $HTTP_RAW_POST_DATA, works, too - but it's slower and needs the PHP configuration always_populate_raw_post_data.
替代方法 using 也$HTTP_RAW_POST_DATA可以工作 - 但速度较慢并且需要 PHP 配置always_populate_raw_post_data。

$HTTP_RAW_POST_DATA should be available assuming the content-type of the request was not multipart/form-data
假设请求的内容类型不是 multipart/form-data，$HTTP_RAW_POST_DATA 应该可用
