Question

I have two arrays and I need to send the array values to PHP. When I print the value that returns from PHP, it prints an empty string. How can I get it? my code is below.

$.ajax({
    type: "POST",
    url: "test2.php",
    data: {
        price: [101, 69, 51],
        id: [1, 2, 3]
    },
    success: function(response) {
        alert(response);
    }
})​;​

In PHP

  $id=mysql_real_escape_string($_POST['id'][0]);        
  echo $id;

Answer 1

Try running var_dump($_POST). That way you can see exactly what the structure of the array is, so you know how to access it.
