Question

I just reviewed my code and I realize that I never use

var

However I read

http://www.php.net/manual/en/keyword.class.php

and it seems to say that one should use var.

<?php
class Cart {
    var $items;  // Items in our shopping cart
     ....blah
}
?>

In this example what privacy is var set to.

For my purposes I just normally do:

private $some_var;
public $some_var;
protected $some_var;

What is best practice?

Answer 1

var is identical to public. BUT most modern coding standards prefer ‘public’ over var.

Howevever, there is no real difference at all.
