php中 __call 與 __callStatic用法與區別詳解

php 5.3 後新增了 call 與callStatic 魔法方法。

call 當要調用的方法不存在或許可權不足時，會自動調用call 方法。

callStatic 當調用的靜態方法不存在或許可權不足時，會自動調用callStatic方法。

call($funcname, $arguments)callStatic($funcname, $arguments)

參數說明：

$funcname String 調用的方法名稱。

$arguments Array 調用方法時所帶的參數。

call 例子

<?phpclass Member{    protected $memberdata = array();    public function call($func, $arguments){        list($type, $name) = explode('_', $func);            if(!in_array($type, array('set','get')) || $name==''){            return '';        }        switch($type){            case 'set':                $this->memberdata[$name] = $arguments[0];                break;                        case 'get':                return isset($this->memberdata[$name])? $this->memberdata[$name] : '';                break;                        default:        }    }}class User extends Member{    public function show(){        if($this->memberdata){            foreach($this->memberdata as $key=>$member){                echo $key.':'.$member.'<br>';            }        }    }}class Profession extends Member{    public function show(){        if($this->memberdata){            foreach($this->memberdata as $key=>$member){                echo $key.':'.$member.'<br>';            }        }    }}$userobj = new User();$userobj->set_name('fdipzone');$userobj->set_age(29);$userobj->show();$probj = new Profession();$probj->set_profession('IT SERVICE');$probj->set_price(2500);$probj->show();?>

callStatic例子

<?phpclass Member{    protected static $memberdata = array();    public static function callStatic($func, $arguments){        list($type, $name) = explode('_', $func);                if(!in_array($type, array('set','get')) || $name==''){            return '';        }        $feature = get_called_class();        switch($type){            case 'set':                self::$memberdata[$feature][$name] = $arguments[0];                break;            case 'get':                return isset(self::$memberdata[$feature][$name])? self::$memberdata[$feature][$name] : '';                break;            default:        }        }}class User extends Member{    public static function show(){        $feature = get_called_class();        if(self::$memberdata[$feature]){            foreach(self::$memberdata[$feature] as $key=>$member){                echo $key.':'.$member.'<br>';            }        }    }}class Profession extends Member{    public static function show(){        $feature = get_called_class();        if(self::$memberdata[$feature]){            foreach(self::$memberdata[$feature] as $key=>$member){                echo $key.':'.$member.'<br>';            }        }    }}User::set_name('fdipzone');User::set_age(29);User::show();Profession::set_profession('IT SERVICE');Profession::set_price(2500);Profession::show();?>
