Answer 1

As described in the JQuery API documentation, you can use

var rootPath="http://example.com/"
var jsonData = $.toJSON({ q: array });
var urlWS = rootPath + "post.php";
$.ajax({
    url: urlWS,
    type: "POST",
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    data: jsonData,
    success: function(result) {
            // do something here with returned result
    }
});

Answer 2

var array= [];
array[0] = 'hi';
array[1] = 'hello';

    $.ajax({
      url: 'http://something.com/post.php',
      data: {array: array},
      type: 'POST'
    });

Answer 3

try like this,

var data_to_send = $.serialize(array);

$.ajax({
            type: "POST",
            url: 'post.php',
            data: data_to_send,
            success: function(msg){

            }
        });

or

you can pass as json like below,

$.ajax({
    type: "POST",
     url: 'post.php',
    dataType: "json",
    data: {result:JSON.stringify(array)},
    success: function(msg){

    }
});

Answer 4

var arr = <?php echo json_encode($postdata); ?>;
ajax: {
                                url:"post.php"    
                                type: "POST",
                                data: {dataarr: arr},
                                complete: function (jqXHR, textStatus) {
                                }

You can try this .this will work

Answer 5

example

ajax code:

$.ajax({
  url: 'save.php',
  data: {data: yourdata},
  type: 'POST',
  dataType: 'json', // you will get return json data
  success:function(result){
   // to do result from php file
  }
});

PHP Code:

$data['something'] = "value";
echo json_encode($data);
