Saving JSON with PHP script leaves file blank

Question

I'm saving some JSON data to a JSON file using this PHP script:

<?php
$myFile = "json/countries.json";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = $_POST["data"];
fwrite($fh, $stringData);
fclose($fh)
?>

And sending the data to the PHP script with this JS function:

saveJson(countries, '/save_countries_to_json.php');

function saveJson(object, file) {

$.ajax
({
    type: "POST",
    dataType : 'json',
    async: false,
    url: file,
    data: { data:object },
    success: function () {alert("Thanks!"); },
    failure: function() {alert("Error!");}
});
}

But the only thing that happens is that the JSON file I'm trying to save the data to is emptied.

If I change

data: { data:object },

to

data: { data:jQuery.parseJSON(object) },

I get

Uncaught SyntaxError: Unexpected token A

What does the 'A' stand for?

If anyone knows what's wrong, please share your wisdom :)

Thanks!

Try this in your php file

<?php
$myFile = "json/countries.json";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = urldecode($_POST["data"]);
$stringData1 = json_encode(json_decode($stringData));
fwrite($fh, $stringData1);
fclose($fh)
?>

Add this in your js file

saveJson(countries, '/save_countries_to_json.php');

function saveJson(object, file) {

$.ajax
({
    type: "POST",
    dataType : 'json',
    async: false,
    url: file,
    data: { data:object },
    success: function () {alert("Thanks!"); },
    failure: function() {alert("Error!");}
});
}
