I am on linux, using apache. The dump shows in the response category of the page inspector, but the browser is not showing the same data.

javascript post code

    const eHttp = new XMLHttpRequest()

    eHttp.open("POST", "post.php", true)

    eHttp.setRequestHeader('Content-type', 'application/json')

    eHttp.send(JSON.stringify(dataMap['user']))

php code:

echo $_POST;

$_POST = json_decode(file_get_contents('php://input'), true);

var_dump($_POST);
