web程序员必须了解的php中 __call 与 __callStatic用法与区别详解

call 当要调用的方法不存在或权限不足时，会自动调用call 方法。

callStatic 当调用的静态方法不存在或权限不足时，会自动调用callStatic方法。

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

参数说明：

$funcname String 调用的方法名称。

$arguments Array 调用方法时所带的参数。

call 例子

<?php

class 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

<?php

class 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();

?>
