Get php array from jquery serialize function sended value

Question

I make a AJAX call, and sends the argument equal to forms's serialize-d value.

var form_data= $('#some-form').serialize();
var data = {
 action: 'my-action',
 data: form_data
 };
$.post(my-file.php,data...){...}

So in my php file var I have a $_POST['data'] = arg1=value1&arg2[arg2_1]=value2... and so on.

It can be a long string with unlimited number of arguments and unlimited depth level.

So the question - is there any function in php, to make such string to an Associative array like this

$my_post[arg1]=value1;
$my_post[arg_2][arg2_1]=value2;
...

Or I need to write that function myself?

• TheWolf: Does that question help you? stackoverflow.com/questions/16003122/…
• Simon: Unfortunately - no. I have to send the data exactly by described way.
• TheWolf: What prevents you from doing it the way suggested in the other question?
• Simon: It is the piece of WordPress plugin, so the WordPress core structure prevents me :)

Answer 1

Use parse_str():

parse_str($_POST['data'], $my_post);
