Why objects (usually) use less memory than arrays in PHP

This is just a small post in response to [this tweet][tweet] by Julien Pauli (who by the way is the release manager for PHP 5.5). In the tweet he claims that objects use more memory than arrays in PHP. Even though it can be like that, it's not true in most cases. (Note: This only applies to PHP 5.4 or newer.)

The reason why it's easy to assume that objects are larger than arrays is because objects can be seen as an array of properties and a bit of additional information (like the class it belongs to). And as array + additional info > array it obviously follows that objects are larger. The thing is that in most cases PHP can optimize the array part of it away. So how does that work?

The key here is that objects usually have a predefined set of keys, whereas arrays don't:

Often I need to display a user-provided picture in an ImageView in such a way that the whole ImageView is filled with as much of the picture possible.

This is how I do it:

var image = require('image');

Ti.Media.showCamera({
        mediaTypes: [Ti.Media.MEDIA_TYPE_PHOTO],
 success: function (e) {

	$.handleItemSwipe = function(_event) {
	var row = _event.source;

	var controls = Alloy.createController("rowControls");
	row.add(controls.wrapper);
