PHP靜態(tài)延遲綁定和普通靜態(tài)效率的對比
PHP靜態(tài)延遲綁定和普通靜態(tài)效率的對比
只是一個簡單的小實驗，對比了下 延遲綁定 和 非延遲的效率
延遲綁定主要就是使用 static 關(guān)鍵字來替代原來的 self ，但功能非常強大了
實驗代碼：
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;
}
}
