Re: context when calling non static method of class in a static way

Simon,

You may want to be careful with the way you declare your class methods.

Example:

public function bar() != static function bar(), even if you use pnysudsfksdljfasdjfsd (::)

See the example below.

class Foo{

static function barStatic()
	{
	echo get_class($this);
	}
public function barPublic()
	{
	echo get_class($this);
	}

}

class Foobar{

public function callBarStatic()
	{
	Foo::barStatic();
	}
public function callBarPublic()
	{
	Foo::barPublic();
	}

}

$oo = new Foobar;
$oo->callBarStatic(); // returns only Foo
$oo->callBarPublic(); // returns Foobar
