Ajax发布到PHP返回空数组

I need to pass a json object from JS to PHP, and it will pass, but the result is an empty array.

Ajax request in 'adopt.php':

var info = JSON.stringify(filteredArray);
$.ajax({
    type: 'POST',
    url: 'ajax.php',
    data: {'info': info},
    success: function(data){
        console.log(data);
    }
});

ajax.php code:

if(isset($_POST['info'])){
    $_SESSION['array'] = $_POST['info'];
}

back in adopt.php, later:

if(isset($_SESSION['array'])){
    $arr = $_SESSION['array'];
    echo "console.log('information: ' + $arr);";
}

in both of the console.logs, it returns an empty object. Does anybody know what could be causing this? (i've tried just passing the json without stringifying it, but it throws a jquery error whenever i do this.)

    To get the response data from PHP, you need to echo your data to return it to the browser.

    In your ajax.php:

    if (isset($_POST['info'])) {
        $_SESSION['array'] = $_POST['info'];
        echo json_encode(['result' => $_SESSION['array']]);
    }
