How to send an array with jQuery .ajax()

Question

I've got an array like this one :

var cars = new Array();
cars['mom'] = "Ford";
cars['dad'] = "Honda";

I want to send the array cars via jQuery .ajax() function :

 var oDate = new Date();
 $.ajaxSetup({
 cache: false
 });
 $.ajaxSetup({ scriptCharset: "utf-8" ,contentType: "application/x-www-form-urlencoded; charset=UTF-8" });
 $.ajax({ 
 url: path+'/inc/ajax/cars.php',
 data: {cars:cars},
 cache: false,
 type: "POST",
 success : function(text){
 alert(text);
 }
 });

How can I read the array on the server side, with my PHP script ?

Thanks !

• kapa: cars is not array, it is an object. Javascript has no associative arrays.
• Cory Danielson: stackoverflow.com/questions/299610/…
• Alex: I found that I only had to create an object at first, not an array. The rest of my code was good : var cars = new Object(); cars['mom'] = "Ford"; cars['dad'] = "Honda"

Answer 1

try using php special array $_POST

Answer 2

$php_array = json_decode($_POST['cars']);

Answer 3

 $.ajax({ 
 url: path+'/inc/ajax/cars.php',
 data: {cars:$(cars).serializeArray()},
 cache: false,
 type: "POST",
 success : function(text){
 alert(text);
 }
 });

php

$arr = $_POST['cars'];
