What should I do if php cannot receive xml data?

About some issues with php accepting xml, simplexml_load_string cannot receive data

These two methods are generally used to accept xml data

Method 1:

file_get_contents('php://input');

Method 2:

simplexml_load_string($GLOBALS['HTTP_RAW_POST_DATA'], 'SimpleXMLElement', LIBXML_NOCDATA);

It is recommended to use method 1, method 2 has been discarded in higher PHP versions

----------------- -------Good-looking dividing line------------------

Foreword: The company's projects are somewhat old, and they all use method 2.

Problem: When I use curl to request an interface written by others, method 2 cannot receive it, but method 1 can.

Solution: After testing, the Content-Type in the cur parameter that needs to be set is text/xml

Code: curl_setopt($curl, CURLOPT_HTTPHEADER, array("Content-Type: text/ xml; charset=utf-8"));

The default value of Content-Type in PHP's cur parameter is application/x-www-form-urlencoded, tmd! Using method 2 will determine the Content-Type of the http request header
