How to pass Array with values using Ajax in jquery and get the values in Php page

Question

I have an ajax posted parameter as below:

$.ajax({
      url:'url',
      data:{ary:my_ary},
  ...

Where value in the my_ary = Array([0]=> Test Text,[1]=> test Text2)

Now i need to get values from this array using a foreach() loop like this:

 foreach($_POST['ary'] as $val){
         echo($val.'<br>');
   }

But it is showning the following error

An invalid arguments passed to foreach loop

just do print_r($_POST); and show the output from the php file — Exprator, Jun 19 '17 at 07:30
send array with json_encode and decode your array in code before loop. — Arshad Shaikh, Jun 19 '17 at 07:31
Is there any jquery / javascript function to decode the array and send it as parameter? and if yes then how i will decode this encoded array in PHP ? — Abdul Rahman, Jun 19 '17 at 07:33

For decode array in php `json_decode();` function is used :) — Arshad Shaikh, Jun 19 '17 at 07:35

Convert the array to a string before passing it like so:

my_ary.join(',');

Or if it's a complex array consider JSON:

JSON.stringify(my_ary);

In case of your associative array

$.ajax({
   url:'url',
   data:{
      my_ary:JSON.stringify(my_ary);
   }

My array looks like: my_ary: Array(++++[0]+=>+Mr.+Justice+Waqar+Ahmad+Seth++++[1]+=>+Mr.+Justice+Rooh-ul-Amin+Khan+) this is the result when checked in browser developers tool – Abdul Rahman Jun 19 '17 at 07:34

$.ajax({
  url:'url',
  data:JSON.stringify(my_ary)

you need parse arrays into the string.

I hope it helps you

Or you can format a query string like this:

var query_string = "action=" +  "action_name" + "&data_id=" + data_id + "&nonce=" + nonce;

... data: query_string,

Can be helpful in future for someone

var jsonString = JSON.stringify(my_ary);
   $.ajax({
        type: "POST",
        url:'url',
        data: {data : jsonString}, 
        
    });
