I have tried examples from all over the globe and all have the same result. I know it must be something simple that I am missing. I am running in a Windows 11 cmd, no errors are returned and it does call the PHP script but can’t get the JSON in the PHP script. I tried http and https as well.

Here is the command:

curl -X POST -H "Content-Type: application/json" -d '{"name":"John Doe","age":30,"city":"New York"}' http://myserver/hello.php

Below is the PHP script, excuse the lines that are commented out for they reflect different things I have tried. Note I want to pass JSON not http://myserver/hello.php?name=John Doe&...

hello.php

<?php
  //header('content-type: application/json');
  //$json = file_get_contents('php://input');
  //$data = var_dump(json_decode($json, true));
  //$data = var_dump(json_decode($_GET, true));
  $data = json_decode(file_get_contents('php://input'), true);
    //$data = json_decode($_POST);
    //$data = $_POST;
  //$dump = print_r($data);
  //$dump = print_r($data);
    //$arrayJSON = json_decode($str_json);
    
  //$data = json_decode($_POST);
  

    file_put_contents('test.txt', $data['name']);
?>
