PHP静态延迟绑定和普通静态效率的对比
只是一个简单的小实验,对比了下 延迟绑定 和 非延迟的效率
延迟绑定主要就是使用 static 关键字来替代原来的 self ,但功能非常强大了
实验代码:
class A { protected static $cc1 = array('a1', 'b', 'c', 'd'); protected static $cc2 = array('a2', 'b', 'c', 'd'); protected static $cc3 = array('a3', 'b', 'c', 'd'); protected static $cc4 = array('a4', 'b', 'c', 'd'); protected static $cc5 = array('a5', 'b', 'c', 'd'); public static function n1() { return static::$cc1; } public static function n2() { return static::$cc2; } public static function n3() { return static::$cc3; } public static function n4() { return static::$cc4; } public static function n5() { return static::$cc5; } } class C extends A { } class B { protected static $cc1 = array('a1', 'b', 'c', 'd'); protected static $cc2 = array('a2', 'b', 'c', 'd'); protected static $cc3 = array('a3', 'b', 'c', 'd'); protected static $cc4 = array('a4', 'b', 'c', 'd'); protected static $cc5 = array('a5', 'b', 'c', 'd'); public static function n1() { return self::$cc1; } public static function n2() { return self::$cc2; } public static function n3() { return self::$cc3; } public static function n4() { return self::$cc4; } public static function n5() { return self::$cc5; } }
