PHP面向对象static和const的两段代码示例

<?PHPclass myclass{static $count;                                     //静态化类属性function __construct(){self::$count++;                                  //static声明的部分用self访问}static function getcount(){return self::$count;}}myclass::$count=0;                      //属性的初始化$c1=new myclass();                     //1$c2=new myclass();                     //2$c3=new myclass();                     //3echo  myclass::getcount();          //访问类里的方法  3echo  $c1->getcount();              //3echo  $c2->getcount();              //3echo  $c3->getcount();               //3?>

<?phpclass myclass{const VALUE="dongdong11019";function showvalue(){return  self::VALUE;}public function getvalue(){return $this->showvalue();}}echo myclass::VALUE;ECHO "<hr/>";$class1=new myclass();echo $class1->getvalue();?>//dongdong11019//dongdong11019
