javascript object to php using jquery ajax

Question

I have an array or a javascript object that I create like this: arr[arr.length]=obj where the obj is a classic JSON string like {\"id\":1}.

Answer 1

Can send the JSON and use json_decode() to turn it into a php array.

$.post('server/path', { jsonData: JSON.stringify(arr)}, function(response){
   /* do something with response if needed*/
});

in php:

$arr=json_decode( $_POST['jsonData'] );
/* return first ID as test*/
echo $arr[0]['id'];
/* or dump whole array as response to ajax:*/
print_r($arr);
