Question

Is it possible to get a PHP array created on another page via AJAX? This is what I have so far:

index.php

$.ajax({
   url: 'array.php', 
   type: 'GET',

   complete: function(data) {
      $('#div').html(data.responseText);
   }
});

array.php

$arr = array('red', 'blue', 'green');
echo $arr; //echo it?

As you can see, I’m trying to load $arr into a div on index.php. Is this possible?

You can’t get it as a PHP array unless you are staying in PHP. You can get it as an array, however, using json_encode:

echo json_encode($arr);

Which can be parsed in javascript.

Use datatype: json (see http://api.jquery.com/jQuery.ajax) or its shortcut, jQuery.getJSON() to read it on the JS side.
