一、獲取靜態方法呼叫者的類名

方法一:
class foo {
    static public function test() {
        var_dump(get_called_class());
    }
}

class bar extends foo {
}

foo::test();
bar::test();

輸出:
    
    string(3) "foo"
    string(3) "bar"

方法二:
class Bar {
    public static function test() {
        var_dump(static::class
 
);
    }
}

class Foo extends Bar {

}

Foo::test();
Bar::test();

Output:

 string(3) "Foo"
 string(3) "Bar"

二、運用call_user_func_array代入物件作用域

<?php
 function  foobar ( $arg ,  $arg2 ) {
    echo  __FUNCTION__ ,  " got  $arg  and  $arg2 \n" ;
}
class  foo  {
    function  bar ( $arg ,  $arg2
 
 ) {
        echo  __METHOD__ ,  " got  $arg  and  $arg2 \n" ;
    }
}


 // Call the foobar() function with 2 arguments
 call_user_func_array ( "foobar" , array( "one" ,  "two" ));

 // Call the $foo->bar() method with 2 arguments
 $foo  = new  foo ;
 call_user_func_array (array( $foo ,  "bar" ), array
 
( "three" ,  "four" ));
 ?>
