Tell if the object is instantiated in a static method?

When calling a static method in PHP, can one tell if the method is running in an instantiated object or not?

Something like

public static function update( $value = NULL) {
  if ( self::is_instantiated() ) {
    update_db($this->value);
  } else {
    update_db($value);
  }
}

I don't want to simply test ! is_null($value) because the method can be called publicly without passing a value.

I tried checking isset() for $this and $this->property, but that didn't work in the non-object context.

Just delete the static keyword. Static method is always static.

class A {
  public function whoami() {
    echo $this ? "i am object\n" : "i am class\n";
  }
}

$a = new A();
$a->whoami();
A::whoami();

Result:

i am object
i am class
