assertInternalType()

assertInternalType($expected, $actual[, $message = ''])

当 $actual 不是 $expected 所指明的类型时报告错误，错误讯息由 $message 指定。

assertNotInternalType() 是与之相反的断言，接受相同的参数。

assertAttributeInternalType() 和 assertAttributeNotInternalType() 是便捷包装(convenience wrapper)，可以应用于某个类或对象的某个 public、protected 或 private 属性。

Example A.25. assertInternalType() 的用法

assertInternalType('string', 42);
    }
}
?>
