If I have an instance in PHP, what's the easiest way to get to a static property ('class variable') of that instance ?
This
$classvars=get_class_vars(get_class($thing));
$property=$classvars['property'];
Sound really overdone. I would expect
$thing::property
or
$thing->property
EDIT: this is an old question. There are more obvious ways to do this in newer PHP, search below.

Static properties are used when we'd like to store class-level data, also not bound to an instance. The syntax is: class MyClass { static property = ...; static method() { ... } } Technically, static declaration is the same as assigning to the class itself: MyClass.
In C#, static means something which cannot be instantiated. You cannot create an object of a static class and cannot access static members using an object. C# classes, variables, methods, properties, operators, events, and constructors can be defined as static using the static modifier keyword.
The static keyword defines a static method or property for a class, or a class static initialization block (see the link for more information about this usage). Neither static methods nor static properties can be called on instances of the class. Instead, they're called on the class itself.
You need to lookup the class name first:
$class = get_class($thing);
$class::$property
$property must be defined as static and public of course.

From inside a class instance you can simply use self::...
class Person {
public static $name = 'Joe';
public function iam() {
echo 'My name is ' . self::$name;
}
}
$me = new Person();
$me->iam(); // displays "My name is Joe"
