PHP does not receive my JSON sent by jQuery AJAX

Question

I have a problem that puzzles me. I have an ajax function that sends a json object, and I see the JSON parsed in the F12 Chrome Headers, and I receive the success alert.

$(document).ready(function() {
        var test = {'bob':'foo','paul':'dog'};
        $.ajax({
            url: "test.php",
            type: 'POST',
            contentType: "application/json; charset=utf-8",
            data: JSON.stringify(test),
            success: function(data) {
                alert("Bien: " + data);
            },
            failure: function(errMsg) {
                alert("Mal: " + errMsg);
            }
        });
});

But in my PHP page I cannot see any POST, anything. I can see that my post is received but anything else:

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
   echo "post"; //Result 'post'
}

foreach( $_POST as $stuff ) {
    echo $stuff; //Nothing at all
}

print_r(json_decode($_POST["data"], true)); // Undefined index: data

In the same code I use

$.post( "test.php", { data: { name: "John", time: "2pm" } } );

and works, then is something related with the code, but I cannot really see waht is it.

Thank you for your help!

What happens when you check $_POST['bob']? Besides, you shouldn't need json.stringify. — Jonast92

try this instead

$results = json_decode(file_get_contents('php://input'));
echo $results->bob //Result foo
