通过jQuery将数组发送到PHP

Question

I have the following div tags that are created dynamically:

<div class="inContainer clonado" data-clone="Si" data-idgaleria="3" data-color="c79471 id=" clone2 ">
<div class="inContainer clonado " data-clone="Si " data-idgaleria="4 " data-color="c6578 " id="clone3 ">

Through drag and drop the element moves in the body. Then in the database I try to save the id of the element and its left and top position.

To capture these properties I am forming an arrangement as follows.

$(".clonado").each(function() {
   var posicion = $(this).position();
   divClonados[$(this).attr('id')] =  [$(this).attr('data-idgaleria'),posicion.left,posicion.top];
});

I already explained this, the problem is when I want to send this arrangement to PHP. I am doing it in the following way:

$.ajax({
      url: url,
      type: "POST",
      data:divClonados,                          
      success: function(data) {
         console.log(data);
      }
});

Is this form bad? And how should you receive them in PHP?
