并不安全的array()比较

	function testComparison() {
		$this->assertTrue(array() == false);  // Pass
		$this->assertFalse(array() == 0); //Fail
		$this->assertFalse(array() == 1); //Fail
		$this->assertTrue(array() == null); //True
	}

bool or null anything Convert to bool, FALSE < TRUE
(bool) null == false, (bool) array() == false;
=> null == array(); false == array();

array anything array is always greater
=> array() > any number;
