## Objects

### Object Initialization

To create a new object, use the new statement to instantiate a class:

`<?php
class foo
{
function do_foo()
{
echo "Doing foo.";
}
}
$bar = new foo;
$bar->do_foo();
?>`

For a full discussion, see the Classes and Objects chapter.

### Converting to object

If an object is converted to an object, it is not modified. If a value of any other type is converted to an object, a new instance of the stdClass built-in class is created. If the value was `NULL`, the new instance will be empty. Arrays convert to an object with properties named by keys, and corresponding values. For any other value, a member variable named scalar will contain the value.

`<?php
$obj = (object) 'ciao';
echo $obj->scalar; // outputs 'ciao'
?>`
