类型的访问修饰符允许开发人员对类成员的访问进行限制,这是PHP5的新特性,但却是OOP语言的一个好的特性。而且大多数OOP语言都已支持此特性。PHP5支持如下3种访问修饰符: public (公有的、默认的),protected (受保护的)和private (私有的)三种。 public 公有修饰符,类中的成员将没有访问限制,所有的外部成员都可...
而且大多数OOP语言都已支持此特性。PHP5支持如下3种访问修饰符: public (公有的、默认的),protected (受保护的)和private (私有的)三种。 public 公有修饰符,类中的成员将没有访问限制,所有的外部成员都可以访问(读和写)这个类成员(包括成员属性和成员方法),在PHP5之前的所有版本中,PHP 中类的成员都是public...
PHP支持的字段作用域有: public、private、protected、final、static (1)public 访问方式: 公共字段可以由相应的对象直接操作和访问。 注意事项:在OOP中并不鼓励使用公共字段,因为直接访问使得类无法很容易地完成某种数据验证。 (2)private 访问方式:指定为私有的字符按不能由类实例化的对象直接访问,也不能由子类使用。
So, it makes sense to rewrite the configuration using object-oriented programming (OOP). Let’s follow the DRY principle (“don’t repeat yourself”) by having a PHP class in the public repository be extended in the private repository. Recreating The Configuration Via OOP Let’s refactor the ...

OOP_guru•Mar 26, 2016 I disagree. I never used 'var' and never miss that. Keep public keyword is ok, but private visibility should be default. Boyd Bueno de Mesquita•Mar 27, 2016 I switch between C# and PHP a lot. I feel that omitting 'public' (and 'private') will take me...
This goes completely against the OOP principles which are natural for PHP devs. I believe that most framework users will not anticipate such rule and try to use protected things as usual. In that case upgradeability of projects will suffer and make things broken even in patch releases (which ...
